ELI5: Explain Like I'm 5

Polysemy

Polysemy is a big word that means one word can have lots of different meanings. Imagine you have a toy box full of different toys. Just like how you have different toys in your toy box, some words have different meanings depending on how they are used.

For example, the word “water” could mean the clear liquid that comes out of the tap, or it could mean a place where you can swim, like the ocean or a pool. Or the word “watch” could mean the thing you put on your wrist to tell time, or it could mean to keep an eye on something or someone.

So when someone uses a word that has more than one meaning, it’s important to pay attention to the context of the sentence to know which meaning they are talking about.
