Forms
ποῖος (poîos) m (feminine ποίᾱ, neuter ποῖον)[1] Ionic κοῖος.[2][3]
Etymology
It is from Proto-Indo-European *kʷo- (“who?”), the interrogative stem, with the suffix seen in τοῖος (toîos) and οἷος (hoîos).[3][1][4] The Ionic form is κοῖος (koîos).[3][2]
Earliest recorded meaning
In Homer it mostly expresses surprise or anger: “what a word you have spoken!” (Iliad 1.552); the Odyssey also uses it in simple questions.[2][5]
Semantic evolution
In comedy and in Plato's dialogues a speaker repeats a word just used with ποῖος, in scornful surprise.[2][5] With the article it asks which of things already mentioned.[5][2] In the New Testament it can mean “whose?”.[5][6]
Medieval Greek pronounced it with synizesis, as ποιος (piós).[7][8] In Modern Greek ποιος (pios) means “who? which?”.[8][9]
