OverdotEdit

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.

UnderdotEdit

Raised dotEdit

  • Number digits in Enclosed Alphanumerics like 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 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.
