+ '''placeō''' (present infinitive placēre, perfect active placuī or placitus sum, supine placitum); second conjugation, optionally semi-deponent^(Wiktionary)
+
+ ==Etymology==
+ It is [[inh|itc-pro|*plak-ē-]], [[inh|ine-pro|*pl(e)h₂/₃k-|t=to agree, be pleasant]], a stative verb beside [[plācō]] “to appease”.^(de Vaan 2008)^(Georges 1913) Its only close cognates are [[txb|plāki|t=agreement, permission]] and Tocharian [[m|xto|plāk-|t=to agree]].^(de Vaan 2008)^(OLD 2012) If the root was [[ine-pro|*plh₂k-]], it might be the same as the root of [[grc|πλήσσω|tr=plḗssō|t=to strike]].^(de Vaan 2008) The Thesaurus reports a view that it first meant “to be flat, smooth”.^(TLL)

+ Plautus uses it.^(de Vaan 2008) Köbler dates Plautus c. 250–184 BC.^(Köbler 2010)

+ ==Semantic evolution==
+ In Classical Latin it was to please, be liked or approved, usually with a dative.^(OLD 2012)^(Lewis & Short 1879) ''Sibi placēre'' was to be pleased with oneself, and it was used of performers who won the audience's favour.^(OLD 2012) Impersonally ''placet'' meant “it is agreed, it seems good”, and as a reply it meant “agreed!”, ''sī dīs placet'' was “God willing”, often ironic.^(OLD 2012)^(Gaffiot 2016)
+
+ The Vulgate's ''placēbō Dominō'' “I shall please the Lord” named the Vespers of the Office of the Dead, and so gave English ''placebo''.^(Etymonline) It survives as [[it|piacere]], [[fr|plaire]] and [[ro|plăcea]].^(Wiktionary)
