§ 76 formation of the 3rd sg. pres. ind. of verbs; thus tereu ‘strikes’: taraw = saif: saf § 173 iv (1). It is seen that when &#8209;eu is the result of affection as above, an a before it is affected to e; see iii (2).

&#8209;óu̯i̯- gives &#8209;yw. Thus W. dilyw ‘flood’ (now generally misspelt diluw) < *dīlóu̯i̯o- < Lat. dīluvium;—distryw ‘destruction’ < *dī-stróu̯i̯&#8209;: Goth. straujan, Lat. destruo ; the vb. is distrywi̯af iv (2);—W. llyw ‘rudder’, < *lóu̯i̯o&#8209;: Ir. lue < *lu-ii̯o&#8209;: Gk. πλόος, √pleu&#8209;;—W. clyw ‘hearing’ < *klou̯i̯- < k̑léu̯es- § 75 vii (1).

&#8209;ā́u̯i̯- became &#8209;ā́i- which gives &#8209;w͡y § 75 i (3); thus W. wy ‘egg’ < Brit. *ā́u̯i̯on < Ar. *ṓu̯i̯om: Gk. ὤιον, ᾦον, Lat. ōvum;—Cornwy < Cornā́u̯i̯&#8209;(a);—Aethwy 1419 < *Oethwy § 78 ii (3) < Octā́vius.

&#8209;ou̯ī́ or &#8209;ou̯i̯´- was similarly simplified to &#8209;o-ī́, &#8209;oi̯´&#8209;, which gives &#8209;w͡y; thus W. dwy ‘two’ f. < *dou̯ī́ < *duu̯ái: Lat. duae, Skr. duvé < *duu̯ái;—W. aswy ‘left (hand)’ < *at-sou̯i̯-ā́: Skr. savyá&#8209;ḥ ‘left’.

&#8209;āu̯ī́, &#8209;āuí- or &#8209;āu̯i̯´- by the shortening of unacc. ā became &#8209;au̯ī́, &#8209;au̯í- or &#8209;au̯i̯´- simplified to &#8209;a-ī́, &#8209;a-í- or &#8209;ai̯´&#8209;, which gives &#8209;oe. The simplification here was late, so that &#8209;au̯ī́ did not, like &#8209;asī́, give &#8209;ei. It did not take place in Bret. and Corn., in which the groups appear as &#8209;ou (&#8209;ow). In W. &#8209;oe generally becomes &#8209;o, 78 i (1). Examples: &#8209;(g)no in proper names; Iud-noe 176, 187, Balch-noe D. G. 43; Gueithgno  144, Guiþno
