This term does not exist in any dictionary either with or without an accent on the i. But if we were to give it a charter of nature as a neologism, it would be with the accent on the i : proserio. . And it occurs to me that it could designate the whole of prose writers, adding a euphonious r to the suffix -io, as happens in terms such as redness or facherío. In power or lordship the euphonic consonant is not necessary, and here the quality of and not the quantity is alluded to.
