inquiry 1906 - eperotema {ep-er-o'-tay-mah}; from 1905; an {inquiry}: -- answer.
inquiry 2045 - ereunao {er-yoo-nah'-o}; apparently from 2046 (through the idea of {inquiry}); to seek, i.e. (figuratively) to investigate: -- search.
inquiry 4226 - pou {poo}; genitive case of an interrogative pronoun pos (what) otherwise obsolete (perhaps the same as 4225 used with the rising slide of {inquiry}); as adverb of place; at (by implication, to) what locality: -- where, whither.
inquiry 4441 - punthanomai {poon-than'-om-ahee}; middle voice prolonged from a primary putho (which occurs only as an alternate in certain tenses); to question, i.e. ascertain by {inquiry} (as a matter of information merely; and thus differing from 2065, which properly means a request as a favor; and from 0154, which is strictly a demand for something due; as well as from 2212, which implies a search for something hidden; and from 1189, which involves the idea of urgent need); by implication, to learn (by casual intelligence): -- ask, demand, enquire, understand.
