‘Affect’ or ‘effect’?
Affect and effect are different in meaning, though frequently confused. Affect is chiefly used as a verb and its main meaning is ‘to influence or make a difference to’, as in the following example sentences:
the pay increase will greatly affect their lifestyle
the dampness began to affect my health
the weather will affect my plans for the weekend
move the cursor until you get the effect you want
The beneficial effects of exercise are well documented
over time the effect of loud music can damage your hearing
When used as a verb effect means ‘to bring something about as a result’. It’s most often used in a formal context as oppose to everyday English:
growth in the economy can only be effected by stringent economic controls
the new policies did little to effect change
the prime minister effected many policy changes
The key thing to remember is that effect is most commonly used as a noun, whereas affect is typically used as a verb.
