Geeks: What is the alphabetical/technical name of this letter or its character: ó?

What is the name of this letter or its character: ó?

Is it called hyphenated? It’s from a name used in LOTR, in other words a fictional language. But there are legit languages that have this letter in their alphabet…so what is this called?

I know it as ‘O Accute’

It is a letter O with an acute accent.

Thanks! [name_f]Do[/name_f] you know if this is also called a long O?
