Pronunciation

  • IPA (Classical): [ˈpɫa.ke.oː][1]
  • IPA (Ecclesiastical): [ˈplaː.t͡ʃe.o][1]

Forms

placeō (present infinitive placēre, perfect active placuī or placitus sum, supine placitum); second conjugation, optionally semi-deponent[1]

Etymology

It is inherited from Proto-Italic *plak-ē-, inherited from Proto-Indo-European *pl(e)h₂/₃k- (“to agree, be pleasant”), a stative verb beside plācō “to appease”.[2][3] Its only close cognates are Tocharian B plāki (“agreement, permission”) and Tocharian plāk- (“to agree”).[2][4] If the root was Proto-Indo-European *plh₂k-, it might be the same as the root of Ancient Greek πλήσσω (plḗssō, “to strike”).[2] The Thesaurus reports a view that it first meant “to be flat, smooth”.[5]

Earliest recorded meaning

Plautus uses it.[2] Köbler dates Plautus c. 250–184 BC.[6]

Semantic evolution

In Classical Latin it was to please, be liked or approved, usually with a dative.[4][7] Sibi placēre was to be pleased with oneself, and it was used of performers who won the audience's favour.[4] Impersonally placet meant “it is agreed, it seems good”, and as a reply it meant “agreed!”, sī dīs placet was “God willing”, often ironic.[4][8]

The Vulgate's placēbō Dominō “I shall please the Lord” named the Vespers of the Office of the Dead, and so gave English placebo.[9] It survives as Italian piacere, French plaire and Romanian plăcea.[1]
