Ok, here's another try with affect/effect.
If you know nouns and verbs this might be helpful -
The majority of the time you use
affect with an a as a verb and
effect with an e as a noun.
As in, the affect (action verb) of the moon will effect (noun) the population.
The affect being the action of the moon and the effect being the result on the population.
Hope this helps a bit (((((((((((((( KD ))))))))))))))
