τίς

Etymology 1
From. Cognates include 🇨🇬 and 🇨🇬. Compare its indefinite form.

In Attic, the labiovelar becomes τ- before the front vowel ι and by analogy also before ου, ῳ in the genitive and dative singular, but π- before the rounded back vowel ο in most of the related interrogatives listed below.

Gen. sg. τοῦ < τέο < (then basis for dat. sg. τῷ and gen. pl. τέων) and the paradigm change to n-stem must have started with *τίν <  elaborated with consonant stem ending, -ᾰ.

Pronoun
