词源

Etymology tree Ancient Greek ϝῖρῐς (wîrĭs) Ancient Greek ἶρις (îris)bor. Latin irisbor. English iris From Middle English iris, from Latin īris, from Ancient Greek ἶρις (îris, “rainbow”). Presuming an earlier form *ϝῖρις (*wîris), possibly from a derivative of Proto-Indo-European *w(e)ih₁-ro- (“a twist, thread, cord, wire”), from *weh₁y- (“to turn, twist, weave, plait”). If so, it would be cognate to English wire.
