inept

Etymology

It is borrowed from Latin ineptus (“unsuited, absurd, foolish”),^{[2][3][4][5][6]} perhaps by way of French inepte (“incapable”), recorded from the 14th century, which Barnhart, Merriam-Webster, Skeat and Weekley give as the immediate source.^{[2][7][8][9][10][11]} The Latin adjective is formed from in- (“not”) and aptus (“fit, suited”),^[3][12][7] with the vowel of aptus changed to e after the prefix;^[12] aptus is the past participle of apiō (“to fasten”).^[13] The word is thus related to apt, adapt and adept.^[13]

Earliest recorded meaning

Not suited to a purpose; without aptitude: 1603, in Florio's translation of Montaigne's Essays.^[2][8] Merriam-Webster dates its first sense to 1542,^[9] and the Shorter Oxford and the Oxford Dictionary of English date the word to the mid 16th century;^[14][5] Hoad records a 16th-century legal sense, "void".^[4]

Semantic evolution

The sense "absurd, foolish" followed in 1604, in King James's Counterblaste to Tobacco,^[2][8] and "out of place, inappropriate" in 1675, in Baxter.^[2][15] Johnson (1755) defined it as "unfit; useless; trifling; foolish".^[16] The sense "lacking in skill, clumsy, incompetent", which the Shorter Oxford dates to the early 17th century together with "foolish", is now the first sense in Collins.^[14][6] In Scots law it meant void, of no effect, a use the OED first records in Scott in 1818.^[2][14] The original sense, unfit for a purpose, is now archaic.^[2][9][14] The noun ineptitude is recorded from 1615, possibly from French, from Latin ineptitūdō.^[8]
