Forms

commercium n (genitive commerciī or commercī); second declension[1]

Etymology

It is from con- (“together”) and merx “goods” with the suffix -ium.[2][1][3] An archaic form ⟨commircium⟩ is cited by a grammarian.[2] Isidore of Seville derived it from ⟨merces⟩, goods for sale.[4]

Earliest recorded meaning

The OLD's first citations are from Plautus, of dealings and relationships.[2] Köbler dates Plautus c. 250–184 BC.[3]

Semantic evolution

It meant buying and selling, trade, commerce, as in Cicero and Livy, exchange, and the right to trade, as in Cicero.[2][5] It meant purchased goods, military supplies, trade routes, and a giving and taking, exchange, with commercium linguae “converse”, as in Livy.[2] It meant dealings, relationship, as in Plautus, sexual intercourse, and the common use of something, as in Suetonius.[2]

In Ecclesiastical Latin it meant dealing, business, commerce, correspondence.[6] In Medieval Latin it meant merchandise, what is given in exchange, gain, and a transaction.[7][8] It survives in French commerce, Italian commercio and Spanish comercio.[1] English commerce came through French in the 1530s, first meaning “social intercourse”.[9]
