Forms

commissārius m (genitive commissāriī); second declension[1][2]

Etymology

It is from Latin commissum (“something entrusted”) + -ārius, from committō (“to entrust”).[3][4][5] Conte calls it a medieval Latin word.[4]

Earliest recorded meaning

The TLL has it only in ancient glossaries, which explain it as notārii, and in a scholium on Juvenal 7.6, where it explains praecōnēs and other readings are ēmissārii and emptiārii.[3] As a word of medieval documents, Köbler finds it in charters of 1152–1190; the MLW's earliest example is a diploma in the name of Frederick I that it marks as spurious, addressed among others to vicars, lieutenants and commissāriī.[1][2]

Semantic evolution

In medieval Latin it was the person to whom a ruler, a pope or a bishop entrusted a task, a jurisdiction or a power of administration: a delegate or commissioner.[6][2][7] In 1230 Archbishop Albert of Magdeburg calls himself legate and commissārius of Rome.[2] In England it named royal and papal commissioners and the commissary to whom a bishop delegated his judicial powers;[7] at Oxford it was the deputy of the chancellor of the university.[7] It also meant the executor of a will,[6][8][9] and in the Czech lands a guardian of orphans or of property.[9] In Scotland the burghs sent commissāriī to parliament.[7] It could also be an adjective, “delegated”, as in the letters by which a case was committed to someone.[7][8]

Neo-Latin kept the word for officials of many kinds;[10] Luther's theses say that trust in letters of indulgence is vain even if the commissary, or the pope himself, pledged his soul for them.[10] English commissary comes from it in the late 14th century, at first mainly in the Church;[5] English commissar also goes back to it, through French, German and Russian.[5]
