What is the accent on a name called?

There isn't a specific term for the accent on a name. It's simply considered part of the orthography, meaning how a name is spelled and written.

However, depending on the specific accent mark, you can refer to it by its name:

* Acute accent: (é, á, í, ó, ú)

* Grave accent: (è, à, ì, ò, ù)

* Circumflex accent: (ê, â, î, ô, û)

* Tilde: (ñ, õ, ão)

* Diaeresis: (ë, ü)

* Macron: (ā, ē, ī, ō, ū)

The specific accent used will depend on the language and the pronunciation of the name.
