rhai ansoddeiriau yn rhedeg un ffordd mewn rhai tafodieithoedd, ac fel arall mewn eraill. Gan fwyaf mae hi'n ddiogel i ddysgwr wyro tuag at ddefnyddio mor/mwy/mwyaf: mae rhan helaethaf ansoddeiriau deusill a mwy yn dderbyniol gyda "mwy" a "mwyaf", ac mae'n debyg gen i (ydw i'n iawn) bod "mor" yn dderbyniol gyda pob ansoddair. ))) cyfrin [cyfrinn- &adj] - (adj.) secret, subtle I think I would be surprised to see this compared by modification, if only because "cyfrinach" is not that word at all. (( cyfyng [cyfyng- &adj] - (adj.) narrow; difficult I think cyfyng, mor gyfyng, mwy cyfyng, mwyaf cyfyng; although "cyfynged" is convincing. ))) diflanedig [diflanedic- &adj] - (adj.) evanescent, fleeting It also means the completed "(having) vanished" doesn't it? (But that probably rarely gets compared.) (( dwyfol - (adj.) divine It would not surprise me to see dwyfoled, dwyfolach, dwyfolaf; though they might not be right for all I know. ))) gofalus [gofalus- &adj] - (adj.) careful This surely goes mor ofalus, mwy gofalus, mwyaf gofalus. (( hoyw - (adj.) alert, lively, spritely; gay, homosexual hoywed, hoywach, hoywaf ))) llond [llont- &adj] - (adj.) full Surely "llond" is a noun: it is a compression of "llonaid" (llawn + -aid, a full-ness, enough to fill; like coflaid cofl + -aid). In something like "llond ei groen", it is not full qualifying his skin, but a fullness qualified by the genitive "of his skin". The adjective is "llawn" and so goes "llawn: llawned, llawnaf, llawnach". Certainly there should be nothing that is "llonted". (( newydd [newydd- &adj] - (adj.) new, novel; fresh I think I favour mor newydd, mwy newydd, mwyaf newydd. ))) od [ot- &adj] - (adj.) odd, strange I would not rule out the possibility that it may go like this in some dialects (in the South?) but it seems to be either odied, odiach, odiaf or with mor od, mwy od, mwyaf od elsewhere. (( poblogaidd [poblogeidd- &adj] - (adj.) popular Usually with mor/mwy/mwyaf? ))) twp [twp- &adj] - (adj.) stupid, dull Typed, something, typaf? Surely not. I think I use and expect mor dwp, mwy twp, mwyaf twp. (( unig [unic- &adj] - (adj.) only, sole; lonely, alone It is probably bad style to compare the one sense, (like "cywir" and "anghywir"...), but I guess that if you want to compare the other, it often if not usually goes with mor/mwy/mwyaf. g
