improvise

Etymology

It is borrowed from French improviser (“to compose and perform without preparation”),^{[2][3][4][5][6]} from Italian improvvisare (“to sing or speak extempore”), earlier improvisare,^[2][7][8] from improvviso (“unforeseen, extempore”), earlier improviso,^[2][4][3] from Latin imprōvīsus (“unforeseen, unexpected”).^[4][7][9] The Italian verb is dated to 1547 and the French verb to 1642.^[2] Etymonline takes the English verb chiefly from Italian and partly from French,^[7] and Barnhart as partly a back-formation from improvisation.^[10] The Latin adjective is formed from in- (“not”) and prōvīsus (“foreseen”), the past participle of prōvideō (“to foresee, provide for”),^[4][9][8] the source of provide.^[9]

Earliest recorded meaning

To compose and perform without preparation, used without an object: 1788, in a translation of Dupaty's travels in Italy.^[2]

Semantic evolution

English first took words for the Italian practice of extempore verse: improvisator in 1765 according to Etymonline,^[7] the adjective improviso in 1753 and improvisation in 1777 according to the OED.^[2] The verb followed, with an object from 1808,^[2] when an article on Italian improvisers in the Athenaeum introduced it as a "new-coined verb" and asked the readers' pardon for it.^[7] Etymonline notes that it was treated as a foreign word, and generally printed in italics, in the early 19th century, and that rivals such as improvisate (1825) and improvisatorize (1828) were tried.^[7] Barnhart and Ayto date the verb to Disraeli's Vivian Grey (1826), where someone is able to improvise quotations,^[10][9] and Merriam-Webster also gives 1826.^[3] From the 1820s the meaning widened from performance to anything invented on the spot, as in French,^[2] then to making something from what is available (1834) and arranging something at short notice (1843).^[2] The sense of making do without an object appeared by 1938.^[2]

Usage notes

The OED's first edition (1899) gave the main stress to the final syllable, probably under the influence of improviso.^[2] This stress fell out of British use early in the 20th century but survives as a variant in the United States.^[2] The first-syllable stress now usual seems to be recorded first in the British Encyclopedic Dictionary (before 1888).^[2]
