Pronunciation

  • UK: /ˌɪntəˈmɪtn̩t/[1]
  • US: /ˌɪntɚˈmɪtn̩t/[1]

Etymology

It is borrowed from Latin intermittēns (“leaving off, ceasing”),[2][3][4][5][6] the present participle of intermittō (“to leave off, pause, interrupt”),[2][3][4][5] formed from inter (“between”) and mittō (“to send, let go”),[3][4][7] the source of mission.[3][4] The verb also gave English intermit and intermission.[3][4] Barnhart allows that the English adjective may instead have been formed from intermit with -ent, on the Latin model.[4][8] The OED compares French intermittent, recorded in 1598.[2]

Earliest recorded meaning

Of a pulse or fever, stopping and starting at intervals: 1603, in P. Holland's translation of Plutarch's Moralia.[2][4] Merriam-Webster dates the word to 1601,[5] Etymonline to about 1600,[3] and the Shorter Oxford and the Oxford Dictionary of English put it in the mid 16th century.[9][10]

Semantic evolution

The word began in medicine, of fevers and pulses that come and go,[2] and after 1693 an intermittent was a noun for an intermittent fever.[2][9] Johnson (1755) defined it as "coming by fits", with a medical quotation about pains.[11] General use, of anything that stops and starts, is recorded from 1675, in Ogilby's Britannia,[2] and in the late 19th century it entered technical terms such as intermittent sterilization in microbiology (1893).[2][9]
