affect

Affect is most often used as a verb meaning “to have an impact on,” as in “The tornado barreling towards us will affect our picnic plans.”

As a verb, affect can also mean “to feign an appearance,” as in, “Don’t let that surfer’s California accent fool you. Although she affects a convincing ‘Dude, that was rad,’ she is from Minnesota and just moved out West last month.” Don’t let that affect your friendship, though, she’s probably really fun.
