Reconstruction:Proto-Germanic/aiks

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”).^[1]
