USAGE
Affect and effect are quite different in meaning， though frequently confused. Affect is primarily a verb meaning 'make a difference to'， as in their gender need not affect their career. Effect on the other hand is commonly used both as a noun and a verb， meaning 'a result' as a noun （ move the cursor until you get the effect you want ） or 'bring about (a result)' as a verb （ growth in the economy can only be effected by stringent economic controls ）. In the British National Corpus， nearly 10 per cent of uses of effect are in fact incorrect uses where affect should be used.
