HI Amy,

affect or effect?

In general use, affect is only used as a verb, whereas effect is commonly used as a noun and only in formal contexts as a verb. What causes confusion is that they have very similar pronunciations and closely related meanings. If one thing affects [acts upon] another, it has an effect on it [causes it to change]. Notice also that you can affect [cause a change in] people as well as things, but you can only effect [bring about] things such as changes: The election has affected our entire society, for it has effected major changes in the government.The bad weather has a bad effect [not affect] on him. … 1861583968

There are five distinct words here. When “affect” is accented on the final syllable (a-FECT), it is usually a verb meaning “have an influence on”: “The million-dollar donation from the industrialist did not affect my vote against the Clean Air Act.”

Occasionally a pretentious person is said to affect an artificial air of sophistication. Speaking with a borrowed French accent or ostentatiously wearing a large diamond ear stud might be an affectation. In this sort of context, “affect” means “to make a display of or deliberately cultivate.”

Another unusual meaning is indicated when the word is accented on the first syllable (AFF-ect), meaning “emotion.” In this case the word is used mostly by psychiatrists and social scientists—people who normally know how to spell it.

The real problem arises when people confuse the first spelling with the second: “effect.” This too can be two different words. The more common one is a noun: “When I left the stove on, the effect was that the house filled with smoke.” When you affect a situation, you have an effect on it.

The less common is a verb meaning “to create”: “I’m trying to effect a change in the way we purchase widgets.” No wonder people are confused. Note especially that the proper expression is not “take affect” but “take effect”—become effective. Hey, nobody ever said English was logical: just memorize it and get on with your life.

The stuff in your purse? Your personal effects.

The stuff in movies? Sound effects and special effects.
