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 Eastern European languages and Vietnamese.

Example characters: ċ/Ċ from Maltese and Irish Gaelic (old orthography), ė/Ė from Lithuanian, ġ/Ġ from Maltese and Irish Gaelic (old orthography), ż/Ż from Polish, etc. In Irish Gaelic the dot is called a sí buailte.

Usage

In Vietnamese, the nặng (low, glottal) tone is repesented with a dot below the base vowel: ạ ặ ậ ẹ ệ ị ọ ộ ợ ụ ự ỵ. The dot above the lowercase i and j (and uppercase İ in Turkish) is not seen as a dot, but rather as part of the character, and the double dots above several Latin letters such as ä, ë etc. are not dots either, but are umlauts or diaereses.

In romanizations of Semitic languages, a dot below a consonant is used to indicate the "emphatic version" of that consonant. E.g. represents emphatic s. In Arabic romanization in particular, is for ghayin.

In IAST and National Library at Calcutta romanization, transcribing Indic languages, a dot below a letter indicates retroflex consonants, while an underdot signifies emphatic consonants.

In Yoruba, the dot is used below the o, the e and the s: those three letters can also occur without dot as another letter.

In mathematics and physics the dot denotes the time derivative as in $v=\backslash dot\{x\}$.
