Pronunciation

  • Classical: [pɫaːˈkaː.bɪ.lɪs][1]
  • Ecclesiastical: [plaˈkaː.bi.lis][1]

Forms

plācābilis (neuter plācābile, comparative plācābilior); third-declension two-termination adjective[1]

Etymology

It is from Latin plācō (“to appease”) + -bilis.[2][3][1] De Vaan takes the verb as probably made from a noun, from Proto-Indo-European *pl(e)h₂/₃k- (“to agree, be pleasant”), with a cognate only in Tocharian A plāk- (“to agree”).[4]

Earliest recorded meaning

De Vaan and Köbler date it from Terence,[4][5] in whose Adelphoe it is more conciliatory to clear oneself in person.[2]

Semantic evolution

In Terence it means fit to appease, conciliatory.[2] More often it means easily appeased, quick to forgive:[2][6] the Rhetorica ad Herennium blames a man who is placable to his enemies and implacable to his friends, and Ovid speaks of the anger of the gods that can be appeased by sacrifices.[2] Cicero and Antony use the comparative, but no superlative is found.[3][6] Seneca calls the thunderbolt that Jupiter sends alone peaceful in intent, unlike the destructive one he sends with other gods.[2] In Church Latin it is "easily appeased",[7] and in medieval Latin it also means propitiatory or expiatory.[8]
