Decorum vs etiquette
Etiquette is the specific set of rules for how to behave in a given social context — the correct fork, the appropriate form of address, the expected greeting. Decorum is more flexible and more fundamental: not the rules themselves but the judgment to know what behavior fits the occasion. Etiquette can be memorised; decorum must be understood. You can follow etiquette mechanically; decorum requires reading the room.
