It comes ultimately from late Latin prōde ‘advantageous’ (source of English proud). This gave Old French prou ‘profit’, which was combined in Anglo-Norman with the causative prefix em- to produce the verb emprouer. This originally meant ‘turn to a profit, turn to one’s advantage’, a sense which survives in English in one or two fossilized contexts such as ‘improve the shining hour’. Modern English ‘make or get better’ developed in the 17th century.=> proudimprove (v.)late 15c., "to use to one's profit, to increase (income)," from Anglo-French emprouwer "to turn to profit" (late 13c.), from Old French en-, causative prefix, + prou "profit," from Latin prode "advantageous" (see proud). Spelling with -v- was rare before 17c. Meaning "to raise to a better quality or condition" first recorded 1610s. Phrase improve the occasion retains the etymological sense. Meaning "to turn land to profit" (by clearing it, erecting buildings, etc.) was in Anglo-French (13c.) and was retained in the American colonies." |
