ἐτεός

Ancient Greek

Possibly cognate with Armenian ստոյգ (stoyg), from Proto-Indo-European *set- (“stable, true”) (Beekes, 2010).

However, compare Sanskrit सत्य (satya), from Proto-Indo-Iranian *Hsatyás, from Proto-Indo-European *h₁s-n̥t-yós, from *h₁sónts, from *h₁es- (“to be”), in addition to Albanian jetë.

neuter accusative singular ἐτεόν (eteón) as adverb, often preceded by εἰ (ei): truly, in fact, rightly
1. (in Aristophanes, interrogative) really?
