Tittle

Diacritical mark, the dot element of the letters i and j

The tittle or superscript dot is the dot on top of lowercase i and j. The tittle is an integral part of these glyphs, but diacritic dots can appear over other letters in various languages. In most languages, the tittle of i or j is omitted when a diacritic is placed in the tittle's usual position, but not when the diacritic appears elsewhere.
