+ ==Pronunciation==
+ * IPA (Classical): [ˈproː]^(Wiktionary)
+ * IPA (Ecclesiastical): [ˈprɔː]^(Wiktionary)
+
+ ==Forms==
+ '''prō''' (+ ablative, accusative)^(Wiktionary)
+
+ ==Etymology==
+ It is [[inh|itc-pro|*prō|t=before]], [[inh|ine-pro|*pro|t=in front of, before]];^(de Vaan 2008)^(Wiktionary) Wiktionary takes the long vowel from an instrumental [[m|ine-pro|*próh₁]].^(de Vaan 2008)^(Wiktionary) A short ⟨pro-⟩ occurs in some old compounds such as [[procul]], [[probus]] and [[proprius]]; the variant ⟨prōd-⟩ before vowels (“prōdeō”) is recent, built after ⟨red-⟩.^(de Vaan 2008) The interjection “prō!” is the same word.^(OLD 2012)
+
+ Cognate with [[osc|pru]] and [[xum|pro-]], [[sa|प्र|tr=pra-]] and [[grc|πρό|tr=pró]].^(de Vaan 2008)^(OLD 2012)
+
+ ==Earliest recorded meaning==
+ It is found in the Twelve Tables and in Livius Andronicus.^(Köbler 2010)^(de Vaan 2008)
+
+ ==Semantic evolution==
+ ''Prō'' first means “in front of, before” (''prō aede Castoris'' “in front of the temple of Castor”, ''prō rostrīs'' “from the speaker's platform”).^(OLD 2012) From standing in front of someone came “on behalf of, in defence of, for”, then “instead of, in place of” (''prō cōnsule'', the source of [[prōcōnsul]]), “in return for”, “in proportion to, according to” and “as, like”.^(OLD 2012)^(Wiktionary)^(Stelten 1995) With ''esse'' it means “in favour of”.^(OLD 2012)
+
+ The interjection ''prō!'' (''prōh'') expresses wonder or grief: ''prō Iuppiter!''^(Lewis & Short 1879)^(OLD 2012) Medieval Latin used ''prō'' for purpose and cause (“for, because of”), and Late Latin increasingly with the accusative.^(Niermeyer 1976)^(Wiktionary)
