plebeian
This term carries a heavy weight of social hierarchy and often implies a judgmental perspective. When used as an adjective today, it is frequently pejorative, suggesting that something is crude, tasteless, or devoid of intellectual depth. It evokes a sense of looking down upon the masses from a position of perceived superiority. In a historical sense, however, it is a neutral sociological descriptor. It identifies a specific legal and social class in antiquity, stripping away the modern connotation of "lack of taste" to focus on the structural divide between the ruling elite and the general citizenry.
Countable when referring to a specific person from the lower class or a Roman citizen. Uncountable when referring to the general social class or status of commoners.
