Decorum

nounPronunciation: /dɪˈkɔː.rəm/

In Portuguese: Decoro

What does “Decorum” mean?

Behavior in keeping with good taste, propriety, and established standards of dignity.

Etymology

A learned borrowing, in the 16th century, of Latin decorum, "that which is fitting", the neuter of the adjective decorus, "proper, becoming", from decor, "grace, seemliness", and decere, "to be fitting". In Roman rhetoric and poetics decorum was the rule that style should suit the subject, the speaker and the occasion, and English first used the word in that sense before extending it to behaviour. Decent and decorate belong to the same Latin family.

Usage note

A formal word, common in accounts of courts, parliaments and ceremonies. The adjective decorous is stressed on the first syllable.
