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.

Dots

Overdot

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

), placing a macron over the vowel (ᑲ = ka, ᑳ = kā), or placing a circumflex over the vowel (ᓄ = no, ᓅ = nô).

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 . In addition, the overdot is one way used to indicate an infinitely repeating set of numbers in decimal notation, as in , which is equal to the fraction 13, and or , which is equal to 17.

Underdot

Raised dot

  • Number digits in Enclosed Alphanumerics: 🄀 ⒈ ⒉ ⒊ ⒋ ⒌ ⒍ ⒎ ⒏ ⒐
  • In Canadian Aboriginal Syllabics, in addition to the middle dot as a letter, centred dot diacritic, and dot above diacritic, there also is a two-dot diacritic in the Naskapi language representing /_w_V/ which depending on the placement on the specific Syllabic letter may resemble a colon when placed vertically, diaeresis when placed horizontally, or a combination of middle dot and dot above diacritic when placed either at an angle or enveloping a small raised letter ⟨ᓴ⟩. Additionally, in Northwestern Ojibwe, a small raised /wi/ as /w/, the middle dot is raised farther up as either ⟨ᣜ⟩ or ⟨ᣝ⟩; there also is a raised dot Final ⟨ᣟ⟩, which represents /w/ in some Swampy Cree and /y/ in some Northwestern Ojibwe.
