§ 151 respec&shy;tively. mor softens the initial of the adj. except when it is ll or rh; but mwy and mwyaf take the radical; thus mwy dymunol Ps. xix 10, Diar. xvi 16 ‘more desirable’.

(1) mwy and mwyaf are only used to compare compounds and deriv&shy;atives where inflex&shy;ional compar&shy;ison is not feasible.

On the other hand forms with mor are, as shown above, different in origin from the equative, and have had a separate existence from the outset. Hence mor is used freely before all adjec&shy;tives at all periods. Thus:

Exclamative: mortru gl. eheu!—Mor truan genhyf mor truan a ẟeryv 1 ‘How sad to me, how sad [is] what has happened.’—Poet emen&shy;digeit y gof ay digones&#8203;…&#8203;mor dost yw  477 ‘Accursed be the smith that made it, so painful is it.’—mor ẟyrys yw  120 ‘so tangled is it.’—mor hagɏr y gwelei y ẟelw ry oed arnaw  251 ‘so ugly did he perceive the appear&shy;ance that he bore.’—mor ẟirẏeit&#8203;…&#8203;mor dec  1385 ‘how bad&#8203;…&#8203;how fair.’
 * Wylo’r wyf lawer afon
 * Drosti hi, mor drist yw hon.—Gut.O., 14967/119.

‘I weep many a river for her, so sad is she.’


 * Truan, mor wann yw’r einioes,
 * Trymed yw tor amod oes!—T.A., 17/201.

‘Alas, how weak is life, how sad is the breaking of life’s promise.’
