Proto-Balto-Slavic

Etymology

Related to *jḗˀgtei (“to be able”) +‎ *-āˀ, probably akin to Ancient Greek ἥβη (hḗbē, “youth, vigour”) (from Proto-Indo-European *yegʷ- / *Hyeh₂gʷ-?). Per Nikolaev (cited by Villanueva Svensson), possibly an example of Narten acrostatic noun.^[1]

Within Slavic, comparison has been drawn to Russian я́глый (jáglyj, “vigorous, energetic”) (of disputed origin).
