The term DOT OVER AN 'I' OR 'J' is a typographical convention used in some languages, such as Spanish and French. The term 'TITTLE' is the 6-letter word used to describe this convention. A TITTLE is a small dot placed over an 'i' or 'j' to differentiate between them, as they are otherwise identical in some typefaces. This convention is used to ensure that words are spelled correctly and to make them easier to read.
