(1) The simple adjectives (or old derivatives no longer recognized as such): bach, ban, call, cas, certh, craff, cu, cun, chweg, da, dig, drwg, fflwch, gau, gwâr, gwir, gwymp, hafal, hagr, hawdd, hên, hoff, llawen, llesg, lion, llwyr, mad, mân, pur, rhad, serfyll, serth, sobr, swrth, teg.
bychain is pl. of bychan, not of bach, which is sg. and pl. like the others in the above list; thus plentyn bach ‘little child’, pl. plant bach.
- Yr adar bach a rwydud
- A’th iaith dwyllodrus a’th hud.—D.G. 313.
‘Thou wouldst snare the little birds with thy deceiving words and thy wile.’
drwg is also an abstract noun, pl. drygau ‘evils’, hagr is included in D.’s list; Rowland’s hagron is obviously spurious—it would be *heigron if genuine. hên is included because henẏon Ỻ.A. 95 is only known to occur once, and that in verse. D. y C. has hyff as pl. of hoff, as well as ag̃hlyff, pryff and cryff as pl. of anghloff, praff, craff apparently extemporized r.p. 1361 (praff has pl. preiffion). mân is usually pl. as in cerrig mân ‘small stones’, often sg. as in gro mân ‘fine gravel’.
glân ‘clean’ has pl. gleinẏon Ỻ.A. 102, r.p. 1236, which is comparatively rare, and became extinct. D. 56 includes tywyll, but quotes an example of tywyllion; this and one or two others like melysion (for melys pl., Diar. xxiii 8) are not uncommon in Late Mn. W.
(2) Adjectives of the equative or comparative degree. But superlative adjectives have substantival plurals.
(3) Derivative adjectives in ‑adwy, ‑aid, ‑aidd, ‑ar, ‑gar, ‑in, ‑lyd, 153. But adjectives in ‑ig, ‑og, ‑ol, ‑us have plurals in ‑i̯on, which commonly precede their nouns, but may follow them, as gwyr bonheẟigẏon s.g. 62 ‘gentlemen’.
nefolẏon wybodeu ac ysprydolẏon gelvydodeu Ỻ.A. 103 ‘heavenly sciences and spiritual arts’, cf. 102. Deddfolion ddynion a ddyfalant m.a. i 26 ‘law-abiding men they deride’. o’r nefolion a’r daearolion a thanddaearolion bethau Phil. ii 10.—Nerthoeẟ nefolẏon… neu wrthẏeu r͑yveẟolẏon Ỻ.A. 102 ‘heavenly powers or wonderful miracles’.
- Y mae’r sir wedi marw Siôn
- Yn wag o wŷr enwogion.—Gut.O., g. 219.
