Ampersand (&) vs. And

The ampersand is the character “&”; the word “and” is ordinary conjunction text. Microsoft house style generally prefers “and” in prose and headings except where an ampersand belongs to a name, interface label, or technical expression, illustrating that the choice is contextual rather than universal.

Quick answer

Use “and” in ordinary prose unless a name, interface, technical expression, or governing house style specifically calls for “&”.

Key details

Core IssueThe ampersand is a distinct character, but whether to use it instead of “and” in prose is a house-style and context decision.
