tic

Pronunciation

• /tɪk/^[1]

Etymology

It is borrowed from French tic,^[2][3][4][5] first known in French as the name of a twitching disease of horses, which Cotgrave (1611) recorded as ticq and tiquet, a disease that suddenly stops a horse's breath and makes it stand still.^[2][5][6] The English word was at first nearly always short for tic douloureux, literally "painful twitch".^[2][3][5] The origin of the French word is unknown.^[3][5][7] Klein thinks it probably imitative, and Dictionary.com expressive;^[8][9] Diez, followed by the OED, compared Italian ticchio (“whim, caprice”),^[2][3][10] from which the Oxford Dictionary of English and the Shorter Oxford derive it,^[11][12] and Collins compares ticche.^[7] Skeat linked it with words for twitching such as German zucken (“to twitch”).^[6]

Earliest recorded meaning

As tic douloureux, a severe facial neuralgia with twitching of the face muscles: 1800, in the Medical and Physical Journal,^[2][5] or 1798 in Etymonline's dating.^[3] Tic alone, for a disease marked by twitching of certain muscles, especially of the face, appears in 1822, in John Mason Good's The Study of Medicine.^[2][5][3]

Semantic evolution

From a horse's disease in French the word passed in English medicine to facial neuralgia and then to any habitual, largely involuntary twitching of muscles, especially of the face, made worse by stress.^[2][12][5] Merriam-Webster dates the sense of a convulsive twitching to about 1834.^[13] From the late 19th century it was also used for a whim (1896),^[2] and Merriam-Webster records the extended senses of a habitual, usually unconscious quirk of behaviour or speech, and of an obsession.^[13] Collins also records a verb, to have such a twitching.^[7]
