Effect or affect?

Here is another pair of frequently-confused words. 'Affect' is a transitive verb. This means it is something you do to something else. Examples of correct usage are:

The weather affected my sales of ice cream

There was a teacher's strike, but my son's class wasn't affected

Other factors can affect the result

Although 'effect' can be used as a verb (one can, for instance 'effect a change') it is more usually used as a noun, a thing. Here are some examples of it being used properly:

The effect of all these changes is significant

The effort involved determines the size of the effect

He was clearly suffering from the effects of his illness
