A homonym is a word that is spelled and pronounced the same as another word, but has a different meaning.
Here are some examples:
* Bat (a nocturnal flying mammal) and bat (a piece of equipment used in baseball)
* Bear (a large mammal) and bear (to carry or tolerate)
* Right (correct) and right (opposite of left)
It's important to note that homonyms can be tricky because they sound the same, but mean different things. This can lead to misunderstandings if you're not careful!
