  • (decimal point): Many Britons employ the American decimal point ⟨.⟩ owing to a general lack of support for the middot character on computers. It remains common in writing done by hand.
  • (Gregg shorthand, letter a): · (dot) is the shorthand form of a in Centennial, Series 90, DJS, Simplified, Anniversary, and Pre-Anniversary shorthand.
  • (addition compound): The IUPAC Recommendations for Nomenclature of Organic Chemistry[1] state: “Centre dots in formulae of (formal) addition compounds, including hydrates, adducts, clathrates, double salts and double oxides, separate the individual constituents. The dot is written in the centre of the line to distinguish it from a full stop (period).”

  1. (neologism, often proscribed) Used in certain forms of gender-neutral writing either before or around the feminine suffix, to avoid both the use of the masculine as the default form and the verbosity of writing out both the masculine and feminine forms.
    étudiant·esétudiantes et étudiantsfemale students and male students
    étudiant·e·sétudiantes et étudiantsfemale students and male students

Usage notes edit

  • Another way to write such forms in gender-neutral writing is to give both the masculine and feminine forms connected by et, the form that goes first being determined by alphabetical order.
  • French-language authorities, such as the Académie française, usually strongly proscribe the practice.

Usage notes edit

  • · can be uniquely represented by the Unicode character U+0387 GREEK ANO TELEIA.
  • In many places, including on Wiktionary, U+0387 is automatically converted to · (U+00B7 MIDDLE DOT). This is because U+0387 is converted to U+00B7 by all Unicode normalizations.
  • In some fonts, · (U+0387) is positioned higher than · (U+00B7), similarly to the top point of a colon (:) or semicolon (;).
