When used as a diacritic mark, the term dot refers to the glyphs "combining dot above" ( ◌̇), and "combining dot below" ( ◌̣) which may be combined with some letters of the extended Latin alphabets in use in a variety of languages. Similar marks are used with other scripts.

Overdot

Language scripts or transcription schemes that use the dot above a letter as a diacritical mark: In mathematics and physics, when using Newton's notation the dot denotes the time derivative as in v=\dot{x}. In addition, the overdot is one way used to indicate an infinitely repeating set of numbers in decimal notation, as in 0.\dot{3}, which is equal to the fraction 1/3, and or, which is equal to 1/7.

Underdot

Raised dot and middle dot

Side dot

The diacritics ** 〮** and 〯, known as Bangjeom (방점; 傍點), were used to mark pitch accents in Hangul for Middle Korean. They were written to the left of a syllable in vertical writing and above a syllable in horizontal writing.
