From Wikipedia, the free encyclopedia

When used as a descriptor or adjective, affect means a change, and usually refers to an emotion or symptom. Affected, when used in a description, refers to fake or intentionally assumed behaviour (a changed behaviour), i.e., an affected accent.

In general, to affect refers to the consequences of a change or the influence a change has on something else. In this sense, it is often confused with to effect, which generally means to cause a change. When used as verbs, effect refers to the cause of a change ("the governor effected a change in policy"), and affect refers to the consequences of that change ("the new policy really affected our family"). An affect also refers to that change ("her affected accent really had an effect on me"; "her affected accent really affected my view of her").
