Tittle

The 'Tittle' is the dot above an 'i' or a 'j'. It was originally used to distinguish 'i' and 'j' from other letters and the mark was originally larger. This fact is useless because the word is so rarely used, and few people have ever heard it. In Turkish, a similar letter has a tittle that distinguishes two different letters, instead of Capital and Lowercase letters.
