Etymology
Origin of Mafia
First recorded in 1870–75; from Italian, earlier maffia “arrogance” (in Sicilian: “bravery, excellence”), apparently a back formation from mafiuso mafioso ( def. )
Explanation
A mafia is a close-knit group, club, or clique. You might privately refer to the kids who ride horses after school as the "equestrian mafia." When mafia is spelled with a lower-case m, it usually means a group with common interests that sticks together, excludes others, and protects its members. It's a flippant use of a word that mainly refers to a criminal organization, the Mafia. When you call everyone in the school play "the theater mafia," you don't mean they're violent criminals — they're just a little dramatic.
