incessant

Etymology

It is inherited from Middle English incessaunt, also incessaunte,^[2][3][4] borrowed from Late Latin incessāns (“unceasing”),^[3][2][5][6] and probably also borrowed from French incessant.^[4][7][5] The OED notes that the French adjective is implied in the adverb incessamment, recorded in 1358, and the Late Latin one in the adverb incessanter.^[7] The Latin adjective is formed from in- (“not”) and cessāns, the present participle of cessō (“to cease, delay, be idle”),^[3][5][2] the frequentative of cēdō (“to go away, withdraw, yield”),^[5][3] from Proto-Indo-European *ked- (“to go, yield”).^[5][3]

Earliest recorded meaning

Never stopping: incessaunte is recorded in 1461, according to Barnhart.^[4] Etymonline has the middle of the 15th century,^[5] Dictionary.com 1425–75,^[6] and the adverb incessantly appears as early as the early 15th century.^[5][8] The OED's first quotation for the adjective is from 1532, in Thomas More's Confutation of Tyndale.^[7]

Semantic evolution

The core sense has not moved: what does not stop, either continuously or by constant repetition.^[7] For a short time in the 16th century the word could also mean endless, everlasting (1557–73).^[7][2] From 1558, in Phaer's Virgil, it was also used like an adverb, meaning without pause.^[7] From 1749, in Smollett, it could describe people in terms of what they keep doing.^[7] Johnson (1755) gave "unceasing; unintermitted; continual; uninterrupted", with quotations from Shakespeare.^[9]
