Pronunciation

  • UK: /ˈpɪvɪtəl/, /ˈpɪvətəl/[1]
  • US: /ˈpɪvɪtəl/, /ˈpɪvətəl/[1]

Etymology

It is formed from English pivot + -al,[2][3][4][5] after French pivotal, recorded in 1835.[2] Pivot is from French pivot (“hinge pin, pivot”), from Old French pivot (12th century),[3][6] which the OED records from 1338, and in figurative use in the name of a dance from 1174–78.[2] The French word is of uncertain origin;[6][7][3] the OED compares Catalan piu (“spindle, pivot”) and Occitan pivèu (“pivot”).[2]

Earliest recorded meaning

Of, relating to, or acting as a pivot; that on which something turns or depends; central, crucial: 1837, in the Shepherd.[2] Merriam-Webster dates the sense "of crucial importance" to 1838,[8] and Etymonline gives 1844 for the figurative sense.[3]

Semantic evolution

The adjective drew on the figurative sense of pivot, "that on which a matter turns or depends", recorded from 1813,[3] so the meaning "central, crucial" was there from the start.[2][3] After the First World War, a pivotal man (or simply a pivotal) was a man thought to have an important role in restarting industry and commerce;[4][2] the noun is recorded from 1918 and is now historical.[2] Specialised uses followed in mathematics, for the pivot of a matrix or determinant (1924), and in linguistics, for pivot grammar (1963).[2]
