Foreign. Noun & adjective. Now rare. Late 18th century.
[French, present participle of chatoyer.]
(Of) iridescent undulating lustre.
I rather like the look of this word, but its heavily Anglicised pronunciation of shat-oi-yunt utterly obliterates it. Personally, when I casually drop chatoyant in conversation (as one regularly has call to do), I use the ever so much classier French pronunciation of shat-wa-yanh.
