102 analog. accentuation for original *dhii̯ə-tó&#8209;; Ml. W. gorffywys, later, with y lost, gorffwys ‘rest’ < *u̯er-q$u̯$ii̯éi&#8209;st&#8209;, √q$u̯$ei̯ēi̯&#8209;: Lat. quiēsco.

Except as above, &#8209;es&#8209;, &#8209;is- before a vowel developed differently from &#8209;ii̯&#8209;, chiefly because post-tonic s did not, like i̯, become ẟ.

In the penult after the accent &#8209;es- > &#8209;i̯&#8209; ; thus Ml. W. tei ‘houses’ < *tigi̯a < *tigesa § 104 ii 2;—W. clyw ‘hearing’ < *klou̯i̯- § 76 v (2) < *kléu̯es&#8209;, nom. *kléu̯os: Ir. clū, Gk. κλέος < *kléu̯os, neut. s-stem.—So &#8209;ep&#8209;: W. ceifn ‘distant cousin’ < *kóm-ni̯ōs < *kóm-nepōt&#8209;s, see § 123 v.

In the penult and ante-penult, when és came before &#8209;e&#8209;, contraction took place, and ése > ei > W. w͡y; thus W. wy&#8209;t ‘art’ < *ése tū < Ar. *esi ‘art’;—W. neithi̯wyr < *nokti di̯éser- § 98 i (3).—So épe: W. twymn < *tepesm(e)n- § 86 i (3).

In the penult &#8209;és- before &#8209;ī- gave oe; thus W. chwaer for *chwoer i (4), Corn. hoer < *su̯ésīr < *suésōr;—W. doe ‘yesterday’ < *désī < *ghði̯esei: Lat. heri, Gk. χθές, Skr. hyaḥ.—Corn. noi ‘nephew’ < *népōts.—&#8209;es- before ī́ prob. gave ei (like &#8209;ii̯- before &#8209;ī́&#8209;, see v), and Ml. W. nei, Mn. nai ‘nephew’ may represent *nepṓts (accented like the f. *neptís: Skr naptī́ḥ).—&#8209;es- before &#8209;i̯´- gave y, as in Ml. W. y ‘his’ < *esi̯ó, y ‘her’ (for e?) < *esi̯ā́s, § 160 iv.

Lat. &#8209;ai̯i̯- > Ml. W. ei, Mn. W. ai as in Mei, Mai ‘May’ < Mai̯i̯us (Sommer 225); Ml. W. Kei < Caius.

Before lost u or o, &#8209;es- or &#8209;is- gives yw (ew); as Ml. W. Ywein, Ewein, later Owein < *Esu-gani̯os: Gaul. Esugen(ios), Ir. Eogan: Gk. Εὐγένιος. So perhaps in the (pretonic) penult: W. gwyw ‘withered’ < *u̯isú&#8209;: Ir. feugud gl. marcor, Icel. visenn: Lith. výstu ‘I wither’, Lat. viēsco.

So īs before lost u or o gives iw, and ais gives oew: W. gwiw ‘good’ < *u̯īsus < *u̯ēsu&#8209;s: Gaul. Visu-rix: Skr. vásu&#8209;ḥ, Gk. εὖ, √eu̯eseu̯&#8209;;—W. gwaew ‘spear’ for *goew § 78 ii (2) < *gaison: Gaul. gaison whence Lat. gaesum: Ir. gae.

Lat. e in the penult gives ew before lost o or u: W. llew
