Now I find that some of us struggle when it comes to the usage of these two words. A little pointers for you so that you won’t get confused anymore!
Five things to remember, people.
Effect means cause; bring about. Example: He effected a change of plans.
Effect means result. Example: What effect did his promotion have on the staff?
Affect means influence. Example: Do the dim lights affect the way you drive?
Affect means emotional expression. Example: He showed little affect when he was sentenced.
Simple enough? :)
