Decorum is proper, polite behavior that fits the rules and expectations of a situation.
It comes from Latin “decorum,” meaning “that which is proper, seemly,” related to “decus,” “grace, honor.” It originally referred to what was fitting or appropriate.
Decorum is like social grammar: invisible rules you only notice when someone breaks them. Every setting—classroom, courtroom, party—has its own version, and we read those rules almost automatically.
Norms of 'decorum' have historically been applied more strictly to women and marginalized groups, policing speech, dress, and behavior in ways that limited their public participation. Men in power often defined what counted as proper decorum.
Use 'decorum' in institutional or procedural contexts, not to enforce gendered expectations about behavior or appearance. Be specific about which behaviors matter and apply standards consistently.
