1) to enquire, ask
2) to ascertain, by enquiry
Part of Speech: verb
Middle voice prolonged from πύθω puthô, a primary word, (which occurs only as an alternate in certain tenses); to question, that is, ascertain by inquiry (as a matter of information merely; and thus differing from G2065, which properly means a request as a favor; and from G154, which is strictly a demand of something due; as well as from G2212, which implies a search for something hidden; and from G1189, which involves the idea of urgent need); by implication to learn (by casual intelligence): - ask, demand, enquire, understand.
