decorum

This term describes a disciplined adherence to social etiquette and behavioral standards. It carries a connotation of restraint and dignity, often associated with formal environments where maintaining a specific image of respectability is paramount. As an uncountable noun, decorum does not have a plural form and cannot be counted with numbers. It is treated as a mass noun, meaning one cannot refer to a single decorum or multiple decorums; instead, it is typically modified by adjectives like high, strict, or lack of.
