Pronunciation

  • Classical: [suˈaː.sɔr][1]
  • Ecclesiastical: [suˈaː.s̬or][1]

Forms

suāsor m (genitive suāsōris); third declension[1]

Etymology

It is from Latin suādeō (“to advise, recommend”) + -tor.[2][1] De Vaan explains the verb as an old causative meaning “to make sweet, render agreeable”, beside suāvis (“sweet”); it goes back to Proto-Italic *swādeje- (“to render agreeable”) and Proto-Indo-European *su(o)h₂d-eie- (“to render tasty”).[3] The same root gives Ancient Greek ἡδύς (hēdús, “sweet, pleasant”).[3]

Earliest recorded meaning

De Vaan and Köbler record it first in Plautus,[3][4] who has mē suāsōre atque impulsōre id factum, “that was done on my advice and at my urging”.[2][5] Lewis & Short and Conte also cite a line of Ennius' Annals, preserved by Gellius.[5][6]

Semantic evolution

It is a person who advises or urges a course of action,[2][5] often with a genitive of what is urged: Cicero writes suāsor et impulsor profectiōnis, of someone who urged and pressed for a journey,[5] and Georges cites suāsor factī and dēditiōnis from Cicero.[7] In politics it is the speaker who supports a proposed law, as in Cicero's suāsor lēgis Cinciae and Livy's suāsor lēgis.[2][7][6] In the schools of rhetoric it named the author of a suāsōria, a speech of advice, in Seneca the Elder.[2][6] Ecclesiastical Latin kept the sense “adviser”,[8] and medieval writers in Britain used it from Bede on, both for one who urges an action and for one who speaks for a cause: Alcuin writes melius est ūnus suāsor vēritātis quam mīlle adūlātōrēs falsitātis, “one advocate of truth is better than a thousand flatterers of falsehood”.[9]
