Here are some examples:
* "There" and "their" and "they're" all sound the same, but have different meanings:
* "There" refers to a location.
* "Their" indicates possession.
* "They're" is a contraction of "they are".
* "To", "too", and "two" are all homophones:
* "To" is a preposition.
* "Too" means "also" or "very".
* "Two" is the number 2.
The term "homophone" comes from Greek roots: *homo* meaning "same" and *phone* meaning "sound".
