词源说明
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.
