What Is a Forward Slash?
A forward slash is a mark mainly used to indicate line breaks, fractions, ratios, paired terms, and dates. (Note that the use of a forward slash in fractions, ratios, paired terms, and dates is better suited to informal, rather than professional, writing.)
When discussing fewer than three lines of poetry in a paper, writers use a slash to show where one line ends and another begins. (Longer poetry excerpts are formatted in indented block text.)
To indicate line breaks in a poem, be sure to insert a space both before and after the slash. However, when using a forward slash in fractions, ratios, paired terms, or dates, do not insert any spaces before or after the slash mark.
