To, Too or Two

To, Too and Two are three words that native English speakers sometimes spell incorrectly when writing.

WHY?
Because these three words are Homophones. A homophone is a word that is pronounced the same as another word but differs in meaning, and may differ in spelling. So To, Too and Two are pronounced the same though both the spelling and the meaning of each word is different.
