`To, Too, Two`
What's the difference between to, too, and two? It's not too difficult to use them, once you take the time to learn what they mean - and do some practicing too.
To
To has two functions. First, as a preposition, in which case it always precedes a noun.
I'm going to the store
He went to Italy
This belongs to David
Secondly, to indicates an infinitive when it precedes a verb.
I need to study
We want to help
He's going to eat
Too
Too also has two uses. First, as a synonym for "also":
Can I go too?
He went to France too
I think that's Paul's book too
Secondly, too means excessively when it precedes an adjective or adverb.
I'm too tired
He's walking too quickly
I ate too much
Two
Two is a number.
One, two, three...
I have two cars
She ate two pieces of pie
The Bottom Line
The confusion between to, too, and two occurs because the three words are pronounced identically.
One: If you're able to replace the word with "also" or "excessively/too much," use too. Two: If the word is a number, use two. Otherwise, you'll want to use to.
