defiant

Etymology

It is borrowed from French défiant,^{[2][3][4][5][6]} the present participle of défier (“to challenge, defy”), in Old French desfier or defier, whose present participle was desfiant or defiant.^[3][4] The Shorter Oxford allows that it may instead have been formed in English from defiance with the suffix -ant.^[7] The French verb, the source of defy, is from Vulgar Latin *disfidō (“to renounce one's faith”), from dis- (“away”) and fidus (“faithful”), from Proto-Indo-European *bheidh- (“to trust, confide”).^[2]

Earliest recorded meaning

Showing open resistance; bold and unafraid: Merriam-Webster dates the first use to 1583,^[3] and the Shorter Oxford to the late 16th century, adding that the word is rare before the mid 19th century.^[7] The OED, which calls it apparently quite modern, has its first record from before 1837, in S. E. Brydges, cited in Worcester's dictionary;^[4] Etymonline also dates it to 1837.^[4][2]

Semantic evolution

The adjective became common only in the 19th century, beside the much older noun defiance, recorded from about 1300.^[7][4] In 1872, in Charles Lever's Lord Kilgobbin, it was also used for "feeling distrust", following the French sense of défiant;^[4] Etymonline compares diffident.^[2] The adverb defiantly dates from the mid 19th century, and defiantness is rare.^[7]
