ἐγγύη

• ἐγγῠ́ᾱ (engúā)

It is usually assumed that this word contains the preposition ἐν- (en-, “in”) + *γύη (*gúē), a lost word for "hand", which is preserved in Avestan 𐬔𐬀𐬎𐬎𐬀 (gauua, “hand”), as well as in ὑπόγυιος (hupóguios, “nigh at end, imminent”). The Avestan form is ambiguous, however, as it can also continue *gabʰa- and be related to Sanskrit गभस्ति (gabhasti, “arm or hand”), which makes the etymology doubtful.

Further, Greek has γύαλον (gúalon, “hollow of a cuirass”), γυῖον (guîon, “hand”), and γύης (gúēs, “earth”), and from other languages, we may adduce Lithuanian gáuti (“to get, obtain”), suggesting a derivation from Proto-Indo-European *gew- (“hand”). See also ἐγγύς (engús, “nearby”).^[1]
