For example, "bark" can refer to the sound a dog makes or the outer layer of a tree.
Here are some other examples of homographs:
* Bat (a nocturnal flying mammal) and bat (a piece of equipment used in baseball)
* Bow (a weapon) and bow (to bend at the waist)
* Can (a metal container) and can (to be able to)
* Fine (a penalty) and fine (of high quality)
* Lead (a heavy metal) and lead (to guide)
It's important to note that homographs are different from homophones, which are words that sound the same but are spelled differently (e.g., "to", "too", and "two").
