iris

History and Etymology for iris

Noun (1)

Middle English, "iris of the eye, the plant Iris germanica," borrowed from Latin īrid-, īris "rainbow, the plant Iris pallida or related species," borrowed from Greek īrid-, îris "rainbow, iridescent halo around the moon, a flame, etc., iris of the eye, the plant Iris pallida or related species," going back to *wīrid-, *wīris, of uncertain origin

Note: Traditionally, Greek îris "rainbow" (for which an original digamma [letter representing the sound w] is assured by an inscription from Corinth and the metrics of epic poetry) has been regarded as a derivative of Indo-European *u̯ei̯H- "plait, wrap," parallel to Germanic *wīr- (see wire entry 1). However, the variant éris recorded by the Greek lexicographer Hesychius, as well as the dubious character of *wīrid- as an Indo-European formation (< *u̯ih₁-r-i-?) has drawn this etymology into question. Perhaps a substratal word.
