Etymology 1

From Middle Welsh deifyaw, from Proto-Brythonic *dėβjɨd (compare Cornish dewi, Breton deviñ) for which Matasović provides two etymologies:

1. from Proto-Celtic *dauyeti, from Proto-Indo-European *deh₂w- (“kindle, burn”) (compare Tocharian A twās, Ancient Greek δαίω (daíō))
2. from Proto-Celtic *degʷyeti, from Proto-Indo-European *dʰegʷʰ- (“to burn”)

By surface analysis, daif +‎ -io.

Verb
