From Latin inquīrō (“to seek for”), composed of in- (“in, at, on; into”) + quaerō (“I seek, look for”), of uncertain origin, but possibly from Proto-Italic kʷaizeō, from Proto-Indo-European kʷeh₂- (“to acquire”). Displaced Middle English enqueren (from Old French enquerre, of the same source) and native Middle English speir (“ask, inquire”).
