This Proto-Germanic entry contains reconstructed words and roots. As such, the term(s) in this entry are not directly attested, but are hypothesized to have existed based on comparative evidence.



May be from Proto-Indo-European *h₂éyǵs (oak), if related to the first component *αἴξ (*aíx) of Ancient Greek αἰγίλωψ (aigílōps), from a root *h₂eyǵ- whence also Lithuanian áižuols, Latvian uôzuōls, Albanian enjë (< Proto-Albanian *aignjā) and possibly Latin aesculus (if earlier *aig-sculus). However all of the supposed Indo-European cognates are of unclear origin, and according to Kroonen this fact along with the root-noun inflection may be indicative of a non-Indo-European substrate origin; compare also Basque ezkur (acorn).
