Wikipedia has an article on:
Broom icon.svg A user suggests that this Translingual entry be cleaned up giving the reason: "The entry is too English for being Translingual as it contains {{lb|en|...}}, and several meanings could be English instead of Translingual. Another example besides the labels: In German the conjunction for "exclusive or" is not more proscribed than the conjunction for "inclusive or". It might also be so in English, as it could be that "s/he" and (maybe: *) "wo/man" are proscribed, while "she/he" and "man/woman" are just sometimes proscribed.".
Please see the discussion on Requests for cleanup(+) or the talk page for more information and remove this template after the problem has been dealt with.


The various uses of the present symbol derive from several sources. The medieval virgule (Latin virgula) was an oblique or vertical line that served as a comma, period, and caesura mark and is still used in literary contexts for the slash marking line breaks. (This mark separately developed as the comma, and caesura mark and some senses of the vertical bar|⟩.) The shilling mark (Latin solidus) was variously written s. or as the long s ſ. This eventually developed into a single unpunctuated slash; its use to separate shillings from pence was sometimes generalized to any currency division. Most mathematical senses derived from the earlier horizontal fraction bar (as in 12), rewritten with a slash by the 18th century to permit fractions to be written on a single line. As a separator and conjunction, it represents an oblique form of the dash or hyphen-⟩. Its use to mark supposed actions derives from command formatting in online chat forums, while its use to comment on preceding text derives from its use in some programming languages to form closing tags. Its present British name stroke derives from its use in telegraphy; its present American name slash gained wide currency from its use in computing.

Usage notes[edit]

  • Various uses may simply be read out, as "even" for currency or "out of" for totals, or generally left unspoken, as with line breaks and date separations.
  • The mark itself was originally known as the virgula or virgule in its medieval use as a form of period or comma. It is now defined by Unicode and ISO as the solidus, a late-19th-century British term for the shilling mark. (Some typographers mistaken label this mark as the virgule and distinguish the solidus as the fraction slash ⟨⁄⟩, but neither historical nor present official use supports such a distinction.) Now generally known by the American term slash, although still frequently known as a stroke in British English. For translations and less common English names, see slash.
