Abbreviation with multiple meanings including Primary Care Clinic, Professional Conduct Committee, or Passenger Car Carrier, depending on context.
Modern acronym formation from the initial letters of various institutional names. The proliferation of such abbreviations reflects 20th-century bureaucratic and technical language development.
