What language contains 36 letters in its alphabet?

The language that contains 36 letters in its alphabet is Georgian.

Here's why:

* Georgian uses the Mkhedruli alphabet, which has 33 letters.

* Georgian also includes three additional letters used specifically for writing church Slavonic texts: ä, ï, ö.

Therefore, it's common to say Georgian has 36 letters, although the three additional letters are not part of the standard Georgian alphabet used for everyday writing.
