Forms
sēdātus (feminine sēdāta, neuter sēdātum, comparative sēdātior, superlative sēdātissimus); first/second-declension adjective[1]
Etymology
Used as an adjective, it is the perfect passive participle from Latin sēdō (“to settle, calm”).[2][3][1] De Vaan explains the verb as a causative of sedeō (“to sit”), first “to make someone sit down”, hence “to appease”.[4]
Earliest recorded meaning
Plautus already has it in the Amphitruo, where a desire that is sedatus is a calm, restrained one: the sense “calm, untroubled”.[2]
Semantic evolution
It describes calm people, their mind and bearing,[2][5] as in Livy's sedato gradu, “at an unhurried pace”,[6][7] and Virgil's sedato corde, “with a calm heart”.[6][7] Cicero uses it of a gently flowing river, as an image of a style,[2][7] and of a settled, quieter time,[2] and of an orator moderate in his use of prose rhythm.[6] The superlative occurs in the Rhetorica ad Herennium (vox sedatissima).[5][6]
English borrowed it as sedate.[8]
