*atiską

Probably from pre-Germanic *h₂ed-isko-, an adjective in *‑isko‑ formed from Proto-Indo-European *h₂ed-, substantivized through ellipsis, perhaps originally *atiskaz akraz (‘grain field’) (Kroonen 2013: 39; Kroonen et al. 2022: 9). Compare Old Armenian հատ (hat), Latin ador, adōris (de Vaan 2008: 25) and Old Irish ad, which may reflect various formations in *h₂ed-, *h₂ed-o- or *h₂ed-os-/‑ōs-/‑ōr. Younger Avestan ‎-𐬁𐬜𐬏.𐬟𐬭𐬁𐬜𐬀𐬥𐬀 (āδū.frāδana-) is a possible but disputed o-grade u-stem comparandum, *h₂od-u-. The cereal meaning may have developed from *h₂ed-, since hulled cereals were parched before dehusking (Kroonen et al. 2022: 9). Pisaniello (2021: 70–73) excludes Hittite 𒄩𒀜𒋻 (ḫa-at-tar /ḫattar/) / 𒄩𒀀𒋻 (ḫa-a-tar /ḫātar/) as a cognate as the predominant geminate spelling implies inherited *t rather than *d. The gender is not certain; Lehmann (1986a: 46, s.v. atisk) posits a tentative neuter for the Gothic reflex; Bosworth and Toller (Bosworth & Toller 2014: s.v. edisc) have neuter for the Old English reflex, and Lloyd and Springer (1988: s.v. ezzisc) have masculine for the Old High German reflex.
