Origin & History of “coy”

Essentially, coy is the same word as quiet, and ‘quiet’ is what it meant when it first came into English (it soon developed to ‘shyly reserved’, and the sense ‘quiet’ died out in the 17th century). Its ultimate source was Latin quiētus, but whereas in the case of quiet this passed directly through Old French, coy came via the more circuitous route of vulgar Latin *quētus, which produced early Old French quei, and later coi, the source of the English word.
