Etymology

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 to mark line breaks in verse. (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, usually attributed to Arabic mathematician al-Hassar), 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

• The mark 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.) The mark is now generally known by the American term slash or forward slash, although still frequently known as a stroke in British English. For translations and less common English names, see slash.
• In most uses such as to indicate date separations and line breaks, the mark is not mentioned when the text is read aloud. In some cases, it is replaced by a term, such as “even” for currency or “out of” for totals.
