seems to be a variant of y, chosen for the f. on the analogy of the usual f. e caused by affection.
ii. Ultimate i-affection, § 69, § 76 v.
No. | Unaffected. | Affected. | Examples. | |||
1 | a | ai or | ei | brân, brain; bardd, beirdd; dal, deil | ||
ɥ | tafarn, tefeirn or tefɥrn | |||||
2 | ae | ai | draen, drain; cỿrraedd, cỿrraidd | |||
3 | e | ɥ | angel, engɥl; ateb, etɥb; seren, sŷr | |||
4 | o | agor, egɥr; ffon, ffɥn | ||||
5 | w | asgwrn, esgɥrn; swrth, sɥrth | ||||
6 | oe | w͡y | oen, ŵɥn; croen, crŵɥn | |||

ɥ | taraw, Mn. W. terɥ |
The change occurs only in the ultima. a or o in the penult becomes e § 69 vi. Final w, being originally consonantal, does not count as a syllable for the purposes of affection: marw ‘dead’, pl. meirw.
As to the forms ai and ei of No. 1, see § 81 iii (1); the form ɥ occurs only in the unaccented ultima, § 69 ii (3).
The form ɥ of No. 7 is not a phonetic development of eu, but is due to false analogy; when taraw had become taro the 3rd sing. pres. ind. terɥ was formed from the latter on the model of agor: egɥr. See § 173 iv (3).
iii. Penultimate affection, § 70. The affecting sound is usually preserved in the ultima, but has in some cases disappeared, § 70 iv.
