Pronunciation

  • /ɪnˈhɪbɪt/[1]

Etymology

It is inherited from Middle English inhibiten,[2][3][4][5] borrowed from Latin inhibitus, the past participle of inhibeō (“to hold in, hold back, restrain, hinder”),[2][6][3][7][5][8] from in- (“in, on”) and habeō (“to have, hold”),[6][4][7][9] with the Latin vowel weakened to i in the compound.[5] The American Heritage Dictionary and Etymonline trace the Latin verb to Proto-Indo-European *ghabh- (“to give or receive”), the root of give.[4][6][3] Etymonline and Barnhart also see the English verb as a back-formation from inhibition, which is recorded earlier, as inhibicioun, before 1387 in Trevisa's translation of Higden's chronicle.[6][10] The OED compares Old French inhibir (later inhiber), Spanish inhibir and Italian inibire.[7]

Earliest recorded meaning

To forbid someone to do something: in the Paston letters of 1425, of a man who said that he and his clerks had been forbidden by the court of Rome to act in the matter.[2] Barnhart dates the verb probably before 1425,[10] and the OED's first quotation is from Capgrave's chronicle, before 1464.[7]

Semantic evolution

The verb began as a term of church law: Hoad and Weekley define the first sense as to forbid or interdict,[11][12] and after 1531 it was used specifically of forbidding a cleric to exercise his office.[7][8] The softer sense "to restrain, check, hinder" appears in Coverdale's Bible of 1535,[7][6][10] and by Johnson's time it stood first: his dictionary (1755) defines the word as to restrain, hinder, repress or check, and only second as to prohibit.[13] The psychological sense, of a mental process holding back an impulse or action, is recorded from 1876, in William James, and was extended from the sense of restraining.[7][6] In the 20th century it became a technical word of chemistry and biology for slowing or stopping a reaction or a process,[14][8] and of electronics for blocking a signal or an operation.[14] The older sense "to forbid a thing" is now rare.[7]
