Frisk Etymological English
αἰγός
Grammatical information: f.
Meaning: goat rarely m. he-goat (Il.). Also a waterbird (Janzén [s. below] 17), a meteor (Arist.) and a star (Aratos).
Dialectal forms: Myc. aikipta \/aigi-pa(s)tas\/ ? goatherd; aikipode, interpr. uncertain
Compounds: αἰπόλος goatherd < *αἰγ-πολος s. s.v. πέλω (cf. Meier-Brügger Gr. Sprachw. 1, 92). αἰγί-βοτος browsed by goats (Od.) Unclear αἰπόλος κάπηλος παρὰ Κυπρίοις H (see Leumann Hom. W. 271ff; to be rejected Latte's corr. ἀί- = ἀεί).
Derivatives: αἰγίς goatskin, q.v.;
Origin: IE [Indo-European]X [probably] [13] *h₂eiǵ-
Etymology: The compounds in -ι- are unexplained (unclear Heubeck IF 69 (1963) 13-21); old is in any case the type αἰπόλος. αἴξ is cognate with Arm. ayc goat (i-stem); see Clackson 88-90, who reconstructs, with Meillet, *h₂eiǵ-ih₂. Zero grade is mostly supposed in Av. īzaēna- of leather, but it is not certain that it refers to the skin of a goat. If the connection is correct, the word would be IE; the word is often considered as an Anatolian loanword in both Greek and Armenian. - See A. Janzén Bock und Ziege (GHÅ 43 [1937 : 5]) 9ff.and EIEC s.v. - The gloss αἶγες τὰ κύματα, Δωριεῖς H. may be a metaphor, s. αἰγιαλός. In Greek geogr. names (Αἰγαί, Αἰγαῖος, Αἴγινα etc.) we may have not the word for goat, Sommer IF 55, 259f. (Pre-Greek), V. Burr Nostrum mare (Würzb. Stud. zur Altertumswiss.) Stuttgart 1932. Connection with *h₂eig- as to jump is rejected by Mayrhofer EWAia 1, 264 as éjati had a labio-velar (also it does not mean jump). Not to Skt. ajá- goat.
