Prose
The word "prose" first appears in English in the 14th century. It is derived from the Old French "prose", which in turn originates in the Latin expression "prosa oratio" (literally, straightforward or direct speech).
Bosinada
Most scholars agree that the word "bosin" comes from "Ambroeus" (Milanese for Ambrose), as Ambrose was a prominent symbol of Milan. Other explanations of the term nevertheless exist. In Milanese dialect, a "bosin" is also someone who comes from Brianza, and G. Crespi reports that the terms is also used more specifically to refer to that part of the Milanese countryside that lies between the Ticino river, the Lambro river, and the mountaines of Varese, and that it directly derives from the name of the Bozzente creek, which was known as "Bosintio" in the past. These etymologies would thus establish a connection between the bosinata and the rural areas surrounding of Milan, which might make sense as the bosinate were conceived as a coarse, uneducated form of poetry that the Milanese might associate with the vulgar people of the "contado". More specifically, scholar Bernardino Biondelli suggests that the first "bosin" were actually from Milan, but that they deliberately adopted a language inspired by that spoken in the rural areas outside Milan, to emphasize the naive character of their compositions.
