  • U+0323 ◌̣ COMBINING DOT BELOW

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:

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.

Letters with dot

Encoding

In Unicode, the dot is encoded at:

  • U+0307 ◌̇ COMBINING DOT ABOVE

and at:

  • U+0323 ◌̣ COMBINING DOT BELOW
  • U+0358 ◌͘ COMBINING DOT ABOVE RIGHT
  • U+1DF8 ◌᷸ COMBINING DOT ABOVE LEFT

There is also:

  • U+02D9 ˙ DOT ABOVE (&DiacriticalDot;, &dot;)
  • U+18DF CANADIAN SYLLABICS FINAL RAISED DOT

Pre-composed characters:
