What is a word the same as another in sounds and spelling but different meaning?

That's a great question! The word you're looking for is called a homograph.

Here are some examples:

* Bat (a nocturnal flying mammal) and bat (a piece of equipment used in baseball)

* Bow (a weapon that shoots arrows) and bow (a knot tied in a ribbon)

* Lead (a heavy metal) and lead (to guide or direct)

Let me know if you'd like more examples!
