perperam (not comparable)[1]

Etymology

It is the feminine accusative of a rare adjective, from Latin perperus (“wrong”), with ⟨viam⟩, “way”, understood.[2][1] De Vaan thinks it possibly an adverb in ⟨-ām⟩ from ⟨*pero-⟩, “on the other side”, the source of Oscan perum (“without”), later strengthened with per-; or, in Nussbaum's analysis, ⟨*per-poro-⟩, “going wrong”.[3] The TLL doubts whether the adverb really comes from that adjective.[4] Döderlein, in the 19th century, took it as a reduplication of Ancient Greek παρά (pará).[5]

Earliest recorded meaning

Köbler dates it from Plautus.[6] In Plautus a character warns someone not to go to the wrong house by mistake.[2]

Semantic evolution

It means incorrectly, wrongly, amiss, of procedure or of information given: the OLD cites a herald who wrongly proclaimed someone not consul but general.[2] It is also by mistake, as in Plautus and in the Bellum Hispaniense.[2] Church Latin glosses it perversely, wrongly, falsely.[7]

Usage notes
