Etymology

It is from Latin iris (“rainbow”), stem ⟨irid-⟩, with the suffix -escent, a learned formation.[2][3][1][4]

Earliest recorded meaning

It is first recorded in 1842 in the dictionary of Mozin and Biber, for what shines with rainbow-like reflections.[2][3]

Semantic evolution

Littré defines it as what reflects the colours of the rainbow.[5] It has stayed a literary word;[4][3][6] Claudel, for instance, uses it in 1906 of a flayed ox, rose et bleu, iridescent et nacré.[2][3] The noun iridescence followed in 1924.[6]
