cursarius (Latin)

Where does "cursarius" come from?

The Latin noun 'cursarius' is formed by combining the noun 'cursus' with the suffix '-ārius'[1]. The root 'cursus' itself originates from 'currō'[2], a verb tracing back to the Proto-Italic form '*korzō'[3][4]. This deeper lineage roots the word in the Proto-Indo-European base '*ḱers-', which simply means 'to run'[3][4]. In Latin, 'cursarius' evolved to describe a 'pirate' or 'sea-raider'[1], though the root also connects to varied concepts like the 'cursus' or church book of incantations and the 'standard horse' used for riding[1].
