improve

improve: [16] The -prove of improve has no direct connection with the verb prove, although the two have come to resemble each other over the centuries. 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.
=> proud

improve (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.
