The three little words - 'to', 'two' and 'too' - can cause problems because they sound the same. Even native English speakers sometimes get them confused. A sign on a shop window in England read: 'Are You Paying To Much For Your Mobile Phone Air Time? Come In And Talk To Us To Find Out.'
The first 'To' should have been spelt 'Too', but why? If you read the sign out aloud, it all sounds okay. But the person writing the sign had made a mistake. If he had followed the three English Clinic rules, he would not have made such a fool of himself.
All you need to do is remember the meanings of 'two', 'to' and 'too' and you will not make any mistakes.
1. 'Two' is the number between one and three.
Example: I have two brothers. How many have you?
2. 'To' is a preposition showing direction. It is also used before a verb to make an infinitive.
