Pronunciation

  • 10th-century Byzantine: /ˈpro.so/[1]

Forms

πρόσω (prósō); comparative προσωτέρω, superlative προσωτάτω.[2][3] Epic and poetic πρόσσω; poetic πόρσω (Pindar, tragedy); Attic πόρρω.[2][4]

Etymology

In Beekes's and Frisk's view it is from Ancient Greek πρό (pró, “before, forward”) with a suffix *-ti̯o-, a frozen instrumental formed like ὀπίσω (opísō), or perhaps a thematic extension of πρότι (próti).[3][5] Chantraine also derives it from the preposition, with the directive suffix *-yō-.[3][5][6] Lasso de la Vega and Wiktionary instead analyse it as πρός (prós) with the adverbial ending -ω (-ō), like εἴσω (eísō).[5][1] The forms πόρσω (pórsō) and Attic πόρρω (pórrhō) belong with it.[3][2]

Earliest recorded meaning

In the Iliad it means “forwards, onwards”, usually with verbs of motion, and also forwards in time, of a man who can think both backwards and forwards.[2][4][7]

Semantic evolution

It was the Epic, Ionic and poetic word, and LSJ notes that Thucydides never uses it and that later Attic preferred πόρρω (pórrhō).[2] With a genitive it meant “far into” something, and figuratively “far ahead” in virtue, wisdom or wickedness (Herodotus, Aristophanes, Plato); τὸ πρόσω was “forwards”, and Aeschylus uses it for the time ahead.[4]

It survived into medieval Greek as a learned and nautical word.[8] In Modern Greek it is a learned word used mainly in the naval command πρόσω ολοταχώς (próso olotachós), “full speed ahead”.[9][10]
