Caerfallwch oedd ffugenw Thomas Edwards (1779-1858), a anwyd ym mhentref Caerfallwch (heddiw Rhosesmor SJ2168) yn Sir Y Fflint. Fei haddysgodd ei hun pan oedd yn brentis cyfrwywr yn Yr Wyddgrug; wedyn yn y flwyddyn 1803 symudodd i fyw i Lundain i weithio fel clerc. Edmygair geiriadurwr hynod William Owen-Pughe, y cyhoeddwyd ei eiriadur Cymraeg-Saesneg mewn rhannau pan oedd Caerfallwch yn ei arddegau diweddar ac ugeiniau cynnar. Yr oedd Caerfallwch yn awyddus i greu geirfa Gymraeg ar gyfer meysydd masnach, diwydiant, ar gwyddorau. Ni dderbyniwyd y rhan fwyaf oi fathiadau; serch hynny, mae dyrnaid ohonynt yn eiriau hanfodol yn y Gymraeg heddiw (pwyllgor, buddsoddi, safon, cyngerdd, nwy, hirgrwn).


Nid oes fawr o werth iw eiriadur erbyn heddiw, ond yr ŷm ni wedi ei atgynhyrchu ar ffurf testun electronig er mwyn gwneud yn fwy hysbys gyfraniad Caerfallwch i eiriaduraeth yn y Gymraeg.


Caerfallwch was the pseudonym of Thomas Edwards (1779-1858), who was born in the village of Caerfallwch (now Rhosesmor SJ2168) in the county of Y Fflint, north-east Walest. Self-educated, he was a saddlers apprentice in Yr Wyddgrug before moving to London in 1803 to work as a clerk. He was an admirer of the eccentric lexicographer William Owen-Pughe, whose Welsh-English dictionary had been published in parts when Caerfallwch was in his late teens and early twenties. Caerfallwch was keen to create Welsh vocabulary in the fields of commerce and industry and the sciences. Most of his creations were not taken into the language - a handful though are now indispensible words in the modern language (pwyllgor = committee, buddsoddi = invest, safon = standard, cyngerdd = concert, nwy = gas, hirgrwn = oval).


His dictionary is of little value today, but we have reproduced it in electronic text so that Caerfallwchs contribution to Welsh lexicography is better known.


Carfallwchs dictionary is not useful for speakers of, or students of, modern-day Welsh - indeed, it would have been of little practical use in his own day. The introduction to mutations, affixes and function words is rather eccentric by todays standards. But though his dictionary is of little value today, but we have reproduced it in electronic text so that Caerfallwchs contribution to Welsh lexicography may be better known.


The electronic text format also helps in the search (via Google, etc) for Welsh words which may occur in nineteenth-century texts but are unlikely to be found in modern Welsh-English dictionaries - cludsaer (= coachmaker), clyryn (= gadbee, gadfly), hafin (= halcyon days), chwithrwd (= hiss), (that is, if we manage to place all the dictionary online eventually).

In presenting this work to the public, I beg to state that it was originally intended for my own instruction, as the amusement of my leisure hours: but not receiving from any existing Welsh Dictionary the full assistance which I required, from the fact that none of them had kept pace with Lexicons of other languages, I was induced to endeavour to supply their defects, by the introduction of new words and terms according to the exigency of modern times. The new words are not thrust arbitrarily into the language, but are constructed on the elementary scale, from monosyllabic roots, indicating collectively the sense of the term.

It has always been my delight to trace the means adopted by the primitive people of
Wales of communicating their ideas to each other. However, discovering a deficiency in the existing words to meet the progressed state of the Arts and



(x006a) (llun 3260)


Sciences, and being convinced of the capability of the language to expand itself so as to express the minutest idea, I made this humble attempt to supply the desideratum.


In the course of many years occupied in this undertaking, I occasionally published, in the Periodicals of the day, a list of words formed from the roots of the language as above described, which met with the approbation of the Literati of Wales.


Being thus encouraged, and being convinced of the correctness of my views, I have been prevailed upon to commit my labour to the Press in its present form, hoping it will, in some measure, accomplish the object intended.

(x007a) (llun 3261)




LANGUAGE, OR HUMAN SPEECH, is the utterance of vocal sounds, by which the conceptions of the mind are communicated: it is acquired by imitation, and rendered intelligible only by usage. Looking at the philosophy of language, we find that it consists of three distinct branches, viz. words, looks, and tones. The language of the eyes frequently supplies the place of that of the tongue: the deaf and dumb use the language of signs. It is evident that nature has endowed beasts and birds of various descriptions with the power of imparting information to their fellows, which may be called the inarticulate language of irrational animals, and incapable of improvement. Whether language be the necessary consequence of society, or a primitive tongue revealed to man by that Being who gave him existence, is with some persons a matter of controversy.

We know nothing of the origin of language, beyond the brief account we have in the Scriptures. We there find recorded a direct communication from God to the progenitors of the human race, conveyed in words which they well understood: otherwise it would have been an act of injustice to charge them with crime, and to punish them for the violation of that which they did not comprehend. To investigate the subject would exceed our limits, and be foreign to our purpose. But when we regard that perfection which characterizes all the works of the Great Creator, it would he inconsistent to suppose that Adam and Eve had not the power of communicating their ideas. And according to the literal interpretation of the historical narration in the Scriptures, the colloquy and arrangement of parties about the forbidden fruit, &c. it does appear that language was the immediate gift of God: and we might further add, that the primitive speech of mankind, if not the language of heaven, was a language familiar to the angels who kept not their first estate.

Before the creation of Eve, the Lord God brought to Adam every beast of the field, and every fowl of the air, to see what he would call them; and. whatever Adam called every living creature, that was the name thereof. In this case it is evident Adam was a free agent, and at liberty to adopt any appellation he pleased: but the names of animals form no part of a language, which, by articulate sounds, conveys the mind of one individual to another. We may here observe that names are to distinguish things, and have no meaning except as conventional sounds. For, had Adam called a snake, an eel; a sheep, a lion; a bear, a cow; a mouse, an elephant; a wren, an ostrich; we should have the same idea of the animals as we have at present under different names.

A rose by any other name would smell as sweet.



(x008a) (llun 3262)


Some authors affirm, that the names of animals and other objects are descriptive terms of some characteristic property or quality they possess; but such a supposition is not founded on fact; for the meaning of all words must be determined by their actual use. For instance, there is nothing in the word march, or horse, that would convey the idea of strength: hebog, or hawk, to denote fleetness: oen, or Iamb, to indicate innocence: dyn, or man, to signify a human being: nor is there any meaning in any word in any language, except such as custom has sanctioned. It is that, and that alone, which attaches ideas to words, without which, they stand merely as empty sounds. Every language therefore is subservient to the human mind.


Concluding as we do that the original speech of man was revealed from heaven, it must have been very precise and simple; precision of ideas would produce simplicity of terms. Natural causes would gradually augment the vocabulary of the first age of the world: man, guided by his intellectual powers, would invent words suitable to the exigencies of social life; thus, a variety of languages, different in composition and sound, would be produced. As population increased, some of necessity would branch from their original stock to different parts of the world; where new objects, new pursuits, and new discoveries, would require the invention of new names, which, by usage and long experience would form a distinct language, intelligible only to those who became familiar with it. It is from these circumstances that we have such a variety of terms of equal value for the same objects; terms imposed by different tribes, at different periods, and in different localities. There appears no kind of affinity in sound, between iar, and hen; ci, and dog; pen, and head; tn, and fire; dant, and tooth; yet the meaning is the same. We must therefore conclude that they are derived from different sources.


Whatever the confusion of tongues mayv have been at Babel, it is evident, from Genesis, chapter tenth, that the dispersion of Noahs family to different parts of the earth happened previous to that event; and that different dialects were spoken before the deluge, which occured about 1656 years after the creation. During so long a period a great variety of dialects would of necessity be formed. Cam forsook the family of Adam, and dwelt in the land of Nod, where his progeny so much increased, that he built a city, and called it Enoch, after the name of his son. Arts and sciences were cultivated in the early ages of the world; the descendants of Cain discovered the arts of architecture, metallurgy, and music, which would require a great number of new phrases, and add to the stock of words they already possessed. We read that the sons of Gomer were in possession of theijr own territories, every one after his tongue and after their families, before the building of Babel was contemplated: and that Shem and his sons spoke a different dialect, from that of Hams family: [Gen. x.20,31).


Nimrods ambitious mind, aspiring to surpass all others in notoriety and grandeur, proposed to perpetuate his name by erecting a city, and a tower whose top would reach the heavens. In so vast an undertaking, it is not likely that the projector could find a sufficient number of experienced workmen without applying to other tribes, speaking different dialects, and having different names for the same kind of things, | which would naturally lead to controversy and strife about words. And not understanding one anothers language, their plans and operations would be frustrated: consequently, they could not proceed with their audacious design: for they left off to build the city, therefore is the name of it called Babel, which signifies confusion.



(x009a) (llun 3263)


Without regard to the expression, the whole earth was of one language and one speech, we have Scripture authority to prove that there were other dialects in existence at the time when this was spoken: and I look upon the phraseology to mean nothing more than what we might say in our days, that England is of one language, and of one speech. At the same time there are but few counties in England that have not their peculiar provincialisms, which a native of London could scarcely understand, although it is called English.

As to the phrase, the people is one, and they have all one language, many are of opinion it means to convey the idea, that they were of one mind, one counsel, and one sentiment about building; and their mutual exhortation in the words, let us make a brick, let us build a city, let us make a name, would show at least an unanimity of purpose. But whether this be the true meaning or not, we are sure that, comparatively speaking, only a small portion of the human race was engaged in the architectural enterprise; and the confusion of tongues could not affect those branches of Noah's descendants who had already retired to other parts of the globe.

Philologists have taken great pains in the vain attempt to trace the original speech of man; and many an interesting hypothesis has been advanced in the enquiry. Some people infer, that as the Hebrew Scriptures are the most ancient writings extant, the Hebrew is the oldest language: that however is merely an opinion. If it were the Hebrew, it could not have originated from Heber, the progenitor of the Hebrews: for he was not born until the sixty-seventh year after the flood. Looking at the genius and the remarkable regularity of the Welsh Language, its comprehensive powers, its adaptation to poetry, its dignified gravity, its capability of representing every object of imagination and of passion, with its simplicity and accuracy of structure, and taking into consideration that many Welsh words are to be found in almost all the known languages of the world, and easily recognized as identical in sound and signification we have as much reason to claim the Welsh as the original, as any of the languages of antiquity. Whatever the original speech of man was, is a matter of conjecture; and to us, can be of no consequence: for the best language is that by which a man can convey his thoughts to another with the greatest perspicuity and ease.

WRITTEN LANGUAGE is the medium of communicating the thoughts of one individual to another, without the organs of speech. It is represented by visible characters called letters, which are conventional symbols, or marks of distinct elementary sounds of the human voice; and also the elements ot syllables and words. The form or shape of the letters is perfectly arbitrary. Different nations adopt different characters for the same sound: for instance, the letters a, e, and k, of the English, are sounded like e, i, and c, of the Welsh.

Athroniaeth llythyrenau ysgiifen
Dysg ryfedd ywn ddiau;
Ynddi cawn i'n llawn wellu,
Dduwdod y celfyddydau



(x010a) (llun 3264)


WE have no mute characters in our orthography; and generally speaking, they have but one sound, which simplifies the language much, and renders it easy of attainment.


To an Englishman, the Welsh Language on paper has a most uncouth appearance, from the number of consonants or double letters, such as dd, ll, ch, ngh, ng, rh, ff, &c. But it must he remarked these double letters represent only one sound. In the Bardic Alphabet, called Coelbren y Beirdd, there were appropriate characters to distinguish them. When the Roman Alphabet was introduced, its types being found inadequate to represent many of the ancient vocal sounds of the Welsh, several attempts were made to establish a proper system of orthography. In the time of Henry VIII., W. Salisbury and H. Llwyd began to use the letter d with a dot under neath to represent dd, and l with a dot underneath for ll. Dr. Griffith Roberts and Roger Smith adopted the same plan. In the reign of Elizabeth, Dr. John David Rhys, Dr. David Powell, and others, adopted dh and th, which were discontinued by the injudicious Dr. Davies, who substituted the dd, ll, ch, ngh, and all the irrelevant letters now in use; and by doing so, he has done more to disfigure and obscure the language, and throw it into disrepute, than all his predecessors: and I am sorry to say, the injury is now beyond the power of being reclined.


Owing to the want of a fixed orthography, and the indiscriminate use of ihe rowels, our ancient MSS. are very defective, and have caused much confusion; for the analysis and meaning of many words can be ascertained only by their use and bearing in composition: consequently, any quotation from old writings ought not to be our guide for imitation.


It is to be regretted that the few honest endeavours which have been made of late years to correct and improve our language have met with so little encouragement. My intention was to adopt Dr. Pughe's orthography, which I consider a decided improvement; but finding the current opinion against me, it was reluctantly relinquished.


Some people have a kind of superstitious attachment to the very wording and syllabication of their Scriptures, and deprecate any attempt to alter their words, lest it should disturb our authorized version of the sacred volume. Bible orthography ought to be as free from defects as any other book; but we cannot consider Bible etymology as the standard of our language, when we have in it such words as temtasiwn, anmhosibl, apostol, testament, portreadu, condemnio, serio, swper, actau, tabernacl, damnedigaeth, brwmstan, appwyntiaw, dirwest, gras, pentecost, doctoriaid, &c., &c. The Bible was held sacred, and in as great veneration ages ago, as it is at present; and had no emendation been made, we should now have the version of those days, of which the following is a specimen:


Llyma synhvyr euegyl Ieuan ebostol hervyd ydyall ar synvyr a rodes duv yr neb ae troes o ladin ygtymraec. 1346 Pughe s Dictionary.


Mi a anvonav dan i Iehwda, hwn a ystraul lysodd Caersalem. 1580. Perri's Rhetoric.


Gwyn ei vyd y gwr ny rodiawdd yn cyccor yr andewolion, ac ny savodd yn ffordd pechatnriei, ac nyd eisteddawdd yn eisteddle yr ei gwatworus.Com. Prayer Book. Ed. 1586.


A phan welawd ef y dyrva, ef a escenawdd ir moneth; a gwedi iddaw eistedd i deuth eu ddiscipulon attaw.Salesbury's version.


The following is from Wickliffe's translation: .

Ye ben salt of the erthe, that if the salt vanishe ewey wherynne schal it be salted? to nothing it is worth over, no but it be cast out, and he defoulid of men. Ye ben light of the world, a citee sett



(x011a) (llun 3265)

on an hill may not be hid. Ne thi teendith not a lantierne and puttith it under a bushel; but oh a candlestik that it give light to alle that ben in the hous. So, schyne your light before men, that thei see youre gode workis, and glorifie your fadir that is in hevenes. Nyle ghe deme that I can to undo the Lawe or the prophetis, I cam not to undo the lawe but to fulfille. Forsothe I sey to you till hevene and erthe passe, oon lettre, or oon title, schal not passe fro the Law till alle thingis be don. Therefore he that brekith oon of these leeste maundementis, and techith thus men, schal be clepid the Leest in the rewme of hevenes; but he that doth, and techith, schal be clepid greet in the kyngdom of hevenes." Barter's Edit.


It will be discovered in the body of the work, that I have made considerable etymological alterations, which, I believe, sound judgment will approve and vindicate.


English terms in chemistry, geology, anatomy, and other sciences, have derived their nomenclatures from the Greek; but in the attempt to compose new words, to fill what I considered a chasm in Welsh literature, my source and authority were the roots of our own language, which are so simple, pure, and copious, as to render it perfectly unnecessary, to have recourse to any other. My chief endeavour was to concentrate the sense in terms consisting of few syllables, and those of a soft flowing character; and at the same time, the etymology being manifestly clear, without the aid of additional words to explain the meaning. For instance, my word for microscope is mwyadyr; from the comparative mwy, greater, or larger; ad, enhansive; and yr, a termination applied to instruments. By referring to our English dictionaries, I find microscope thus explained: "An optical instrument contrived to give to the eye a large appearance of many objects which could not otherwise be seen." Here are twenty-one words used to expound one; whereas the combination of ideas respecting it exists in one word, mwyadyr.


The word which I have adopted for telegraph is pellebyr; from pell, distance; eb, to impart or communicate; and the termination yr. Our neighbours explain the word thus: "An instrument that answers the end of writing, by conveying intelligence to a distance through the means of signals." Telescope, pellwelyr; from pell, distance; gwel, sight, or that which is seen; and yr;"A long glass by which distant objects are seen." Committee, pwyllgor; from pwyll, deliberation; and cor, assembly, company: thus explained in English: A body of persons selected to examine or manage any matter. Broker, rhyngfaelydd; from rhwng, between; mael, traffic; and ydd, a termination of the masculine gender : "One who does business for others; a go-between." Numerous examples might be added to illustrate the principle on which new words are founded; but as they will be found incorporated in the work, these few must suffice.


Some people attach so little importance to the roots'of our language, as to endeavour to derive them from other roots of a prior existence; and thus diminish their original value. But we have many scores of words that would puzzle the most critical etymologist to trace from any source whatever, and therefore must be considered as primitive. What sense can be made of such words as the following, if they were dissected? cefn, pen, dant, boch, bys, bawd, ewin, coes, loes, poen, oen, dafad, buwch, llo, bustach, giwartheg, dyn, mab, merch, da, drwg, oer, brwd, dwr, tir, ty, mur, ci, cath, cyw, ceffyl, casseg, colomen, ysguthan, bran, pren, maen, craig, &c., &c.


These simple elementary words bearing a peculiar signification which custom has established, cannot with any degree of propriety be mangled into derivatives.


The pedantic attempts which have been lately made to destroy our venerable language, by dividing and subdividing its roots to the mere composition of alphabetical letters, and by applying a particular meaning to each letter, are quite fallacious: and any one who would take the trouble of bringing the matter to a test, will find it not only void of foundation, but perfectly ridiculous. At the same time it must be admitted that some of the vowels have a peculiar import.



(x012a) (llun 3266)


Our vowel sounds are seven; namely, a, e, i, o, u, w, y: five of which are also words, which we shall notice hereafter. The vowels in the English language are represented by seven characters, but they give existence to more than fifty varieties of sounds.


Some of our vowels are so situated in words that, unless they are carefully articulated in their original names, the emission of voice in the utterance, has a strong tendency to change them into the sound of different letters; for instance, The vowel e in such words as oen, poen, croeii, oes, loes, aeth, llaeth, has a close similarity to the sound of u.


The y, appears to assume the sound of u, in monosyllables; as byd, byr, bryn, ffydd, cyf, dyn, &c.: but when these words occupy a relative situation, as byd-ol, byr-dra, bryn-iau, ffydd-lon, dyn-ion; the y retains its original character.


Y also, sounds like u in the termination of words; such as melyn, mochyn, gwenyn, brodyr, llythyr, awyr, swydd, dysgedydd, &c.


The apparent changes, are chiefly owing to the proximity of sounds, and the somewhat difficult manner of giving each its distinct articulation.




FOR the purpose of promoting the harmony of the language, there are certain substitutions or changes in the letters composing the roots, which are called mutations: that is, particular radical letters are modified, or changed into others, under certain forms of construction. For instance, tad, father; dy dad, thy father; fy nhad, my father; ei thad, her father. Thus, the t is changed into d, nh, and th. The first change, d, is called the soft sound; the second, nh, the aspirate; the third, th, the light. No Welsh word commences a sentence with an inflected consonant; for the rules of inflection require to be governed by a preceding word. Popular practice has violated thih rule, and gives an instance of the m taking the soft sound of f, in the pronoun my, my; fy mab

anwyl, my dear son; fy ngharedig gyfaill, my beloved friend.


The mutable consonants are nine; viz. c, p, t, b, d, g, II, m, rh. The first three , undergo three modifications each; by being softened, they change into g, b, and d; aspirated, they become ngh, mh, and nh; and by assuming the light sound, they change into ch, ph, and th.


B and d, by being softened, change into f, and dd: aspirated, they become m, and n.


G, having no soft and light sounds, disappears in words beginning with that letter;

aspirated, it changes into ng.


LI, m, and rh, take only the soft sound of I, f, and r.


The words soft, aspirate, and light, have been adopted by authors, more to distinguish the class, than as appropriate terms expressing the correct sounds of the mutations; and I have employed them in the same sense, although none of such terms define so fully, as to be free from objection.


The rules for the permutation of the mutable consonants are as follow: -


(x013a) (llun 3267)


The initials of verbs take the soft sound, when preceded by other words: .

Gad imi redeg: let me run radix rhedeg.
Ni allaf fyned: I cannot go radix myned.
Mi gerddais yno: I walked there radix cerdded.

Dwr neu laeth: water or milk radix llaeth.

Llaeth neu ddwr: milk or water radix dwr.

Dyn neu ddynes: man or woman radix dynes.

Pen neu droed: head or foot radix troed.




This sound is governed by the possessive pronoun my, or fy, my:

Fy nghefn: my back radix cefn.

Fy mhlant; my children radix plant.

Fy nhroed; my foot radix troed.

Fy mwyd: my food radix bwyd.

Fy ngair. (my word) radix gair.


The aspirate is assumed after the preposition yn, in:-

Ein hiaith: our language radix iaith.

En helw: their possession radix elw.




This sound is assumed after the possessive pronoun ei, her :

Ei chath: her cat radix cath.

It takes the light sound after the adverb tra, over, beyond:

Tra thost: over severe radix tost.

Tra phell: over far radix pell.

Tra chelfydd: beyond skilful radix celfydd.

Tra chethin: beyond hideous radix cethin.


This sound becomes light after the conjunctions a, and; and the preposition, , with; oni, unless.

Bara a chaws: tread and cheese radix caws.

Buwch a chorn: cow with a horn radix corn.

Oni phaid efe : unless he ceases radix paid.

Oni thewi di: if thou art not silent radix tewi.



(llun 3269)

Ni chredaf: I will not believe radix credu.
Ni theimlodd: he felt not radix teimlo.
Na phecha: sin not radix pechu.
Na phrysura: do not hurry radix prysur.

The light sound occurs after the numericals tri, three; and chwe, six:

Tri chorff: three bodies radix corff.
Tri phlentyn: three children radix plentyn.
Chwe throed: six feet radix troed.
Chwe'thy: six houses radix ty.

South Wales this last example is deviated from. They say chwech cosyn, six
cheeses, chwech troed, six feet, &c.

We shall now proceed to notice more particularly, the mutation and power of letters, together with the prefixes and affixes which constitute important features in varying the sense of primitive words, and also shew their frequent misapplication.

Addfwyn, meek, gentle. -, ..

An, as a prefix, is equivalent to the English dis, un, im, in, ir, and mis; which imply a negative; privative; void; destitute. The prefixes af, and di, are of the same import. For the sake of harmony, one prefix is adopted in preference to the other; and also, when the initials of certain words cannot be affixed to them. For instance, af cannot be joined to words beginning with b, c, d, e, ff, g, h, p, s, t; while an and di, can.


According to the principles of the language, the c in all words, such as call, cof, car, cor, cyfarwydd, cyfiawn, Crist, &c. must take the mutation ngh when subjoined to an, and annghall, annghof, annghar, annghor, annghyfarwydd, annghyfiawn, annghrist, is the genuine way of spelling; but for the purpose of softening the sound, one n is now dispensed with.

Anmhrydlon, from prydlon, seasonable.

sound, is omitted:

Anorphen, or diorphen, endless, infinite, radix gorphen.

Anallu, inability, impotence, radix gallu.

Analar, dialar, mournless, griefless, radix galar.


We have several words beginning with an, whose etymology and meaning are at variance: for instance

Anrhydedd, according to the etymology, means without display, or superfluity. The word for honor, or reverence, ought to be enrhydedd.



(x021a) (llun 3275)

Anuwg, or anog, our word for incitement, literally means the reverse; viz. idle, slothful, eagerless, &c , for awg or og, signifies, ardency, animation, full of life, and motion: hence ogyn, ogen, ogau, diog, &c.-It appears to me thnt the word for incitement, or incentive should be either ynog or enog. - Anog is also written annog, derived it is said from the negative an, and dog, which means a proportion or share: but how such derivations can be made to signify incitement or impulse, is more than I can discover.

Anadl or anadyl, is the current term for breath; and by referring to our dictionaries we find that adyl means breath also; if such be the case, anadyl ought to mean breathless, or waning breath. How are we to reconcile such contradictions? Several more words of a similar character might be introduced, as anal, anaele, ancwyn, anaws, anifel, &c.

Anerch, our word for greeting, or salutation, according to the spelling, signifies, direless, or void of terror. The word should be enarch; from en, and arch, solicitation, entreaty.

Annedd, our word for dwelling, must be derived from either an-nedd, or an-dedd; nedd signifies a dingle; nits;dedd, a statute, or rule: such derivations will be seen at once to be inapplicable to a place of residence. The word should be anedd, from an negative and edd, moving, going; hence a dwelling or fixed abode. See Edd.

Anllad, literally, means graceless, or favourless, as lld signifies, blessing, favor, good, &c.:enllawd, or enllod, would be a more appropriate word for wanton, lascivious, lewd. Llawd signifies, wanting, craving, empty, loose; hence tlawd (ty-llawd,) empty house; llawd, a lad; llodes, a young unmarried woman; llodedd, a state of craving, or want: llodineb, lewdness, lechery; llodyr, loose trousers.

Ar, a prefix, augmenting the meaning of words; like gor, it signifies high, super,
great, very, &c
Arfri, high dignity.
Arfraint, high privilege.
Arddigon, superfluity,
Arddyledus, highly incumbent.
Arben, a sovereign.
Argoll, great loss.
Arddolef, great cry.

At, a preposition, to:

Dos at y drws; go to the door.

Some authors suppose that at is a prefix, corresponding to ad, which does not appear to be correct. See Ad.

Au, a plural termination of nouns:
Llyfrau, books.
Penau, heads.
Bochau, cheeks.
Byrddau, tables.
Ffynonau, fountains.
Cwpanau, cups.
Delwau, images.

When cyd is applied to words beginning with t, I should consider it expedient to preserve the radix, and to change the d in the prefix into t, in such words as cyd-daeru, cyd-darddu, cyd-deithi, cyd-draul. We should then have

Cyttaeru (taeru), to debate together.

Cyttarddu (tarddu), to spring together.

Cytteithi (teithi), innate qualities.

Cyttraul (traul), joint waste.

This principle is adopted in ysbytty, diotty, llettrodi, &c.: cydtaeru, cydtarddu, cydteithi, cydftraul, would show the etymology better, though the sound would not be so flexible.

Cym, is a prefix which almost in all cases might be substituted by cy, and thus prevent double consonants coming together, which to an accomplished eye renders their appearance vulgar. The double m in cymmod, cymmal, cymmaint, cymmysg, cymmydog, &c. is quite unnecessary; for they neither exemplify the meaning of the words, nor is their insertion consistent with the genius of the language. If three ms were admitted successively, they would be absorbed into one sound, from the impracticability of giving utterance to more. By excluding one m, we should then have cymod, cymal, cymaint, cymysg, cymydog: the original tendency still remains, the etymology is equally conspicuous, the construction more simple, and the words in appearance more elegant; in either case, the m in the last syllable is not inflected.

Some people maintain that double consonants are necessary to ascertain the right pronunciation and the signification of many words, such as pennau, tonnau, cannu, hynny, tannau, &c. No one acquainted with the rudiments of the language would for a moment advocate such a system. There cannot be two opinions, but that pen, ton, can, hyn, and tan, are the roots of the words adduced, and that nau, nu, ny, are terminations not recognizable in the Welsh language.

There are several words spelled alike, but of which the meaning is different; for B instance -

Ton, a wave.

Tn, tone,

Glan, a brink.

Gln, clean.

Tan, under.

Tn, fire
Can, white.

Cn, a song.

Man, a place.

Mn, small.
Bar, a bar.

Br, fury.

Ber, short.

Br, spear.

Gwar, the nape.

Gwr, mild.

Gwal, wall.

Gwl, a bed.

Gwan, feeble.

Gwn, a stab.

Gwen, (fem.) white.

Gwn, smile.

Mor, how.

Mr, the sea.

Moch, sudden.

Mch, pigs.

The manner in which these words are invariably distinguished in conversation throughout the Principality is by pronouncing the short and the long sounds of the vowels: and as to appearance on paper, the appropriate circumflex mark of the long sound over the letter is a sufficient distinction to any unprejudiced mind. Cyn, prefixed to words beginning with d, changes that letter into n:

Cynnal (dal), to sustain.

Cynnadl (dadl), colloquy.

Cynnefin (defin), accustomed.

Cynnarpar, (darpar), mutual preparation.

If these words were spelled with only one n, both the etymology and sense would be
equally clear.

De, is occasionally used as a termination;
Trymdde, drooping, sad

Esgardde, separation.
Eurdde, covered with gold.

Y dydd eddyw, this day, or the day passing on. It would appear that eddyw is the correct way of spelling the word for day, and not heddyw, derived from hedd. Some dictionaries say, that hedd, not only signifies peace, and tranquility; but also, what glides, or that glides onward: on investigation however, such a meaning as the latter, cannot be substantiated.See anedd under the prefix an.

Having thus taken a somewhat partial view of the rudiments of our ancient language,

which, from the extraordinary nature of its structure, its vast capacity and variety of powers, must have required much time, and have engaged the intense thoughts of a civilized body of mankind to systematize and establish, I now submit the undertaking to the public, with a full conviction that it will be received in the spirit with which it is offered.
