Etymology

Origin of modify

First recorded in 1350–1400; Middle English modifien, from Middle French modifier, from Latin modificāre “to impose a rule or pattern, regulate, restrain”; equivalent to mode ¹ + -ify

Explanation

To modify is to change or transform, but only slightly. If you miss your free-throws half the time, your coach will probably try to improve your shooting average by modifying your technique. Modify may mean to alter something, but it's not a total makeover. When you modify or make modifications, you're making subtle changes. These tweaks are usually needed to make improvements or make the thing being modified less extreme. So you can modify your voice if your tone is too harsh, or modify your wardrobe with a few new pairs of cool shoes.
