Etymology and origin of the Latin word porro

Confidence
Uncertain
First attested
c. 250–184 BC, Plautus

Forms

porrō (not comparable)[1] An archaic porod may be found in an inscription from Praeneste.[2][1]

Etymology

The origin is uncertain.[3][1] It is very like Ancient Greek πόρρω (pórrhō, “forward, far off”) in form and use, and the OLD calls it cognate with that word and its older form πρόσω (prósō);[2][3] ancient grammarians connected them,[1] but the older Greek form does not match the Latin well, and adverbs are seldom borrowed.[1] Köbler traces it to Proto-Indo-European *porsōd (“beside, near”), from the root of *per- (“forward, through”).[4] Nussbaum, reported by de Vaan, tentatively derives it from Proto-Indo-European *pro- with an adverbial ⟨*-s⟩ and the ending ⟨-ō⟩ of intrō and ultrō, through ⟨*prs-ō⟩ and ⟨*porsō⟩.[1]

Earliest recorded meaning

Köbler dates it from Plautus,[4] who has inde ībis porrō in lautumiās lapidāriās, “from there you will go on to the stone quarries”.[2]

Semantic evolution

Porrō is “straight on, forward, onward” in space, and in time “hereafter, in future” (Plautus: gubernābunt doctius porrō, “they will steer more wisely in future”).[2][1] With a continuing action it is “on, further” (porrō loquere, “go on speaking”), and it introduces a further stage, “in turn”, a new item, “besides, next”, and a new argument, “furthermore, moreover”.[2][1][5] In early, poetic and Late Latin it is also static, “far off, yonder”.[1]

Church Latin glosses it “farther on, afterwards, next, furthermore, then”.[6]
