Nguồn gốc từ

ine-proqsb-grc From Middle English iris, from Latin īris, from Ancient Greek ἶρις (rainbow). Presuming an earlier form *ϝῖρις, 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 wire.
