improvise: improvise: [19] Etymologically, if you improvise something, it is because it has not been ‘provided’ for in advance. The word comes via French improviser from the Italian adjective improvviso ‘extempore’, a descendant of Latin imprōvīsus ‘unforeseen’. This in turn was formed from the negative prefix in- and the past participle of prōvīdere ‘foresee’ (source of English provide).

The earliest recorded use of the verb in English is by Benjamin Disraeli in Vivian Grey 1826: ‘He possessed also the singular faculty of being able to improvise quotations’. (The closely related improvident ‘not providing for the future’ [16] preserves even more closely the sense of its Latin original.)
