A homograph is a word that has the same spelling as another word, but a different meaning and sometimes a different pronunciation.
Here are some examples:
* "Lead" can be a metal (pronounced "led") or a verb meaning to guide (pronounced "leed").
* "Bat" can refer to a nocturnal flying mammal or a piece of equipment used in baseball.
* "Bow" can refer to a weapon made of curved wood or a knot tied with a loop.
Homographs can be tricky for learners of English, as they can cause confusion. However, they are a fun part of the language and can make for interesting wordplay!
