I can remember learning about affect and effect in school--and being completely confused all of the time. Is that how you feel? Well, get ready to be relieved of your affect/effect phobia!
Generally speaking, you can count on Affect being a Verb and Effect being a Noun. So how does this help you?
That will not AFFECT the outcome--Verb meaning influence or alter
Her job did not AFFECT her college studies---Verb meaning influence or alter
What is the EFFECT of her test scores?--Noun meaning result
This will have no EFFECT on my performance---Noun meaning result
So...just remember RAVEN--and you will always use the proper AFFECT/EFFECT! Remember Affect is a VERB and Effect is a Noun.
