+ '''oportet''' (present infinitive oportēre, perfect active oportuit); second conjugation, impersonal, no passive, no supine stem^(Wiktionary)
+
+ ==Etymology==
+ It is [[inh|itc-pro|*op-wort-(ē-)]], formed from *op “towards” and the root [[ine-pro|*wert-|t=to turn]] of [[vertō]].^(de Vaan 2008)^(TLL)^(Wiktionary) Walde and Hofmann took it as a causative *uort-eie-, but de Vaan prefers the perfect stem [[ine-pro|*ue-u(o)rt-]], so “it has turned towards someone”, hence “it befits”, with the second conjugation added for its stative sense.^(de Vaan 2008) Others take the first part from [[ob]] or from [[opus]], comparing [[m|la|opus est]].^(Wiktionary)^(Lewis & Short 1879) The OLD calls it doubtful.^(OLD 2012)
+
+ ==Earliest recorded meaning==
+ De Vaan dates it from Naevius.^(de Vaan 2008) Köbler dates Naevius c. 235–200 BC.^(Köbler 2010)
+
+ ==Semantic evolution==
+ It meant “it is demanded by some principle, it is proper, right”, often rendered by English “ought”, as Plautus' ''quid mē oportet facere?''.^(OLD 2012) It also expressed a confident prediction, “it is bound to happen”, and a presumed fact, “it must surely be the case”.^(OLD 2012) Cicero says that ''oportēre'' denotes the perfection of duty, and Döderlein distinguishes it, a duty of morality and honour, from [[necesse est]], a necessity of nature, and [[opus est]], a need.^(Gaffiot 2016)^(Döderlein 1874)
+
+ ==Timeline==
+ * c. 235–200 BC – Naevius uses it.^(de Vaan 2008)^(Köbler 2010)
+ * c. 250–184 BC – Plautus asks what he ought to do.^(OLD 2012)^(Köbler 2010)
+ * 81–43 BC – Cicero says it denotes perfect duty.^(Gaffiot 2016)^(Köbler 2010)
