To - too - two
To, too and two are homophones that have caused confusion to generations of writers in English. It saves much time to learn them thoroughly.
Two is the number ‘2’.
Too (pronounced long) means
- a) as well, also. E.g. "I like coffee. I like tea too."
- b) over much, surplus. E.g. "The weather is too hot for me."
To is the spelling for all other meanings of words that sound like this. It tends to be pronounced very short. Sometimes it sounds like ‘teh’, or can be written (in slang) as ‘gotta’
An short example of a sentence which may help you be clear is the (rather abusive) e-mail note: "Two fingers to XXX too."
