What does biz mean?
"Biz" is an informal abbreviation of "business," used to refer to commercial activity, an industry, or someone's trade or profession. It carries a casual, insider tone, which is why it thrives in phrases like "show biz" and "the music biz" — settings where speakers want to sound relaxed and in-the-know rather than corporate. Though it originated as American slang, likely within the entertainment industry, it is now widely understood across the English-speaking world and appears in journalism, conversation, and popular culture. Grammatically it behaves exactly like "business": it can be modified by adjectives ("a tough biz") and used with articles ("the biz"). Because of its colloquial register, it suits informal speech and headlines but is best avoided in formal documents, where the full word "business" remains the standard choice.

"Biz" is one of the rare words born entirely from show business — it started as backstage slang and became so mainstream that dictionaries gave it a full entry.

Etymology of biz
"Biz" arose as a phonetic respelling and clipping of "business," first appearing in late 19th-century American slang, particularly in theatrical and show-business circles. It belongs to the same family of playful abbreviations as "flu" (influenza) and "bike" (bicycle). Its root traces back through Middle English "bisinesse" to Old English "bisignis," related to the adjective "busy." The clipped form gained lasting popularity through the phrase "show biz" and is now fully established in major dictionaries.
