What do you call 2 words that are spelled the same but sound different?

What is a heteronym?

A pair (or group) of heteronyms are words that have the same spelling (they are homographs) but different pronunciation (they are heterophones) and also different meanings.

It's much easier to grasp this idea with a few examples:

Excuse - Please excuse me while I think of an excuse.

Polish - Tell the Polish cleaners to polish the floor.

Minute - The button was so minute that it was a minute before I found it.

Wind - Hopefully the wind will be strong enough to wind the windmill.

Record - It's the referee's job to record the new world record.

I mean like "wind" in the wind blew hard last night, and wind your watch.

Homonymy-two words sound and are written the same but are different in meaning.

Homograph-words spelled the same but pronounced differently.

I like to read so I read a book. I don't know what they're called but they are strange.

Just don't bring that topic up, and you won't have to worry what you call it.

I think it's call homonym

homophone i think
