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

See also: Anusvara

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

See also: Nukta

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