mafia

This term carries a heavy connotation of secrecy, loyalty, and intimidation. While it originally referred to specific Sicilian criminal organizations, it now evokes a general image of an impenetrable inner circle that operates outside the law or standard ethical boundaries to maintain power.

When used in a non-criminal sense, such as in professional or academic circles, the word is typically used pejoratively. It suggests a claustrophobic environment where nepotism and gatekeeping prevent outsiders from succeeding, transforming a professional network into a restrictive oligarchy.
