IPA: //ˈvɜːrɡjuːl//
KK: /ˈvɜrɡjuːl/
A diagonal mark used in writing and printing to separate options, indicate the word 'per', or show the ends of lines in poetry.
In the phrase 'and/or', the virgule helps clarify the options.
Virgule comes from the Old French 'virgule', which is a diminutive form of 'virge' (meaning rod or twig). The term originally referred to a small rod or a mark used in writing, which evolved into its current meaning as a punctuation mark (the slash).
Think of a small 'rod' or 'twig' ('virge') used in writing, which helps you remember that a virgule is a punctuation mark.
