What’s the difference? The main use of 'affect’ – with an 'a’ – is as a verb meaning to have an influence. So you could say: 'Your emotional state affects how you remember things’. The word with an 'e’ – effect – is usually used as a noun and it means the result of an influence. So: 'What effect will the new law have on road use?’ Part of the problem,
you see, is not only that these two words are spelt very similarly, often pronounced the same, but their meanings are also very similar – one’s a noun, one’s a verb. There is a rarer and more formal use of 'effect’ as a verb – that’s the one with the 'e’ – meaning 'to make something happen’. So you could say: 'It is pointless to try and effect a change in policy now’.
