As you can probably see, "effect," is the most generally fitting word. Encompassing almost every scenario except where emotions and their related influence get involved, and the word becomes "affect."

You can substitute effect with execute and affect with influence. Thus, "The two-party coalition executed the passage of the tax program, which will influence almost every taxpayer."
(I got this from Bernstein's THE CAREFUL WRITER, a very good book on English style.)
Hitting your brakes will affect your speed.
Hitting your brakes will have an effect on your speed.
to affect = to have an effect on
to effect DOES NOT EQUAL to have an affect on
Both words have other meanings, but this is where 90% of the confusion is.
Eric probably has the best solution, always use 'effect' as a noun and 'affect' as a verb.
So - if you're using effect as a verb, always double check.
So where could I find a credible source to back that up. I'm willing to believe what Eric said, but I would like to have it backe dup. Reference it to some source that will define each words a s a verb, rathe rthan just noun form.
