Question 1

Is "affect" a verb?

Accepted Answer

Yes. "Affect" is almost always a verb, meaning to influence or change something: the weather affected our plans. In everyday writing, affect is the action and effect is the result.

When you want the verb, reach for affect — when you want the result, reach for effect.
