coitiō f (genitive coitiōnis); third declension[1]
Etymology
It is from Latin coeō (“to come together”) + -tiō.[2][1] ⟨coeō⟩ is from con- and eō (“to go”), which de Vaan traces to Proto-Italic *ei- (“to go”), from Proto-Indo-European *h₁ey- (“to go”).[1][3]
Earliest recorded meaning
The OLD's earliest citation is from Terence's Phormio, prīma coitiō est ācerrima “the first encounter is the fiercest”.[2][4] Köbler also lists the Twelve Tables, which he dates about 450 BC; he dates Terence 190–159 BC.[5]
Semantic evolution
It meant a meeting, encounter, as in Terence; a coming together, assemblage, as in Cicero; a political combination or conspiracy, as in Cicero's letters to his brother; and in Apuleius a physical or chemical union of elements.[2][6]
In Medieval Latin it meant an encounter, fight.[7] English coition (1540s, “a coming together”; sexual sense from the 1610s) is from it.[8]
