means An organized crime network built on loyalty, intimidation, and a cut of everyone else's business.

from The word surfaces in 19th-century Sicilian dialect, where 'mafia' described boldness, bravado, or a defiant attitude toward authority — not crime itself. It became attached to Sicily's secretive criminal brotherhoods as they grew powerful, especially after Italian unification, and the name rode with Sicilian emigrants to America, where it hardened into shorthand for organized crime generally. The deeper root before that is murky — various Arabic-influenced theories get proposed, but none are settled fact, so honestly, the trail goes cold before the word became famous.
