Gambetta 2009: "The mafia's principal activities are settling disputes among other criminals, protecting them against each other's cheating, and organizing and overseeing illicit agreements, often involving many agents, such as illicit cartel agreements in otherwise legal industries. Mafia-like groups offer a solution of sorts to the trust problem by playing the role of a government for the underworld and supplying protection to people involved in illegal markets ordeals. They may play that role poorly, sometimes veering toward extortion rather than genuine protection, but they do play it." Gambetta, Diego (2009). Codes of the Underworld: How Criminals Communicate.

According to Giuseppe Guido Lo Schiavo [it], "cave" in Arabic literary writing is Maqtaa hagiar, while in popular Arabic it is pronounced as Mahias hagiar and then "from Maqtaa (Mahias) = mafia, that is cave, hence the name (ma)qotai, quarrymen, stone-cutters, that is, mafia." (Loschiavo 1962: 27-30). See: Fabrizio Fioretti (2011), Il termine "mafia", Sveučilište Jurja Dobrile u Puli.
