Something that annoys me is the incorrect usage of to and too. There are three words that sound the same but mean entirely different things, to, too and two. Learn to use them please!
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.
Another one is when people use loose when they should use lose.
This confusion can easily be avoided if you pronounce the word intended aloud. If it has a voiced Z sound, then it’s “lose.” If it has a hissy S sound, then it’s “loose.” Here are examples of correct usage: “He tends to lose his keys.” “She lets her dog run loose.” Note that when “lose” turns into “losing” it loses its “E.”
OK, one more. No one is two words. It's very annoying when people type noone.
