# Dot (diacritic)

(Redirected from )

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:

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 ${\displaystyle v={\dot {x}}}$ . In addition, the overdot is one way used to indicate an infinitely repeating set of numbers in decimal notation, as in ${\displaystyle 0.{\dot {3}}}$ , which is equal to the fraction 13, and ${\displaystyle 0.{\dot {1}}{\dot {4}}{\dot {2}}{\dot {8}}{\dot {5}}{\dot {7}}}$  or ${\displaystyle 0.{\dot {1}}4285{\dot {7}}}$ , which is equal to 17.

### 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.

## Encoding
