Use italics to discuss terms

This page describes two circumstances when we italicize terms that we're introducing or discussing.

For more information about italics and other formatting, including HTML and Markdown formatting for italics, see Text-formatting summary.

New terms

When you introduce a new term that you're defining immediately, use italics on the first mention of the term. Don't use bold or quotation marks.

Recommended: A Clos network is a kind of multistage circuit switching network.

Words as words

When you refer to a word, phrase, or letter in reference to the word, phrase, or letter itself (sometimes called words as words) use italics. Don't use bold or quotation marks.

Recommended: Don't use & (ampersand) as a conjunction. Use the word and instead.

Recommended: To form a possessive of a singular noun, add 's to the end of the word.
