What is the term for something characteristic of commoners?

The term that signifies something characteristic of commoners is plebeian. This word originates from the Latin 'plebeius,' which referred to the lower social classes in ancient Rome. In modern usage, it describes anything that is associated with the everyday person or the lower socioeconomic classes. It can also imply a lack of refinement or sophistication, often contrasting with the elite or aristocratic classes.

The other terms do not convey the same meaning related to commoners. Ponderous suggests something heavy or clumsy, lacking agility or lightness both physically and metaphorically. Nonchalant refers to a state of being casually calm and relaxed, often appearing unconcerned. Penitent describes a feeling of remorse or regret for wrongdoing; it does not pertain to social class. Thus, plebeian most accurately embodies the characteristics associated with commoners.
