Writing & Everyday abbreviation · Everyday

bros. stands for Brothers, an everyday abbreviation also used in business.

Shortens "brothers," most familiar in company names such as Warner Bros. and in casual reference to siblings or close friends. Capitalized, it marks a family business founded by brothers.

Example: Warner Bros. was founded in 1923 by four brothers: Harry, Albert, Sam and Jack Warner.

Usage notes

Nintendo's Super Mario Bros. (1985) made the abbreviation familiar to millions of players. Company names keep it as part of the legal name, so it should not be expanded in references to the firm. As slang, "bros" are male friends, from "bro," a clipping of brother.
