When used as a diacritic mark, the term dot is usually reserved for the Interpunct ( · ), or 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 Central European languages and Vietnamese.

Overdot

Language scripts or transcription schemes that use the dot above a letter as a diacritical mark:

The overdot is also used in the Devanagari script, where it is called anusvara.

In mathematics and physics, when using Newton's notation the dot denotes the time derivative as in v=\dot{x}. However, today this is more commonly written with a prime or using Leibniz's notation. 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 13, and 0.\dot{1}\dot{4}\dot{2}\dot{8}\dot{5}\dot{7} or 0.\dot{1}4285\dot{7}, which is equal to 17.

Underdot

The underdot is also used in the Devanagari script, where it is called nukta.
