Okay kiddo, let's talk about acute in phonetics. When we say "acute," we're talking about a certain kind of mark that can be put on a letter to show how to say it. This mark looks like a little slanted line that points up to the right.
If a letter has an acute mark, it means you should say that letter with extra stress or emphasis. Have you ever heard someone say a word like "ocean" and really emphasize the "shun" sound at the end? That's the kind of stress an acute mark can show.
In some languages, like Spanish or French, they use acute marks on certain letters to show how to say them. For example, in Spanish, the letter "e" with an acute mark (é) sounds different from the letter "e" without the mark.
So, acute in phonetics is just a mark that helps us know how to say certain letters with more emphasis or a different sound. Pretty cool, huh?
