Pronunciation
Forms
πρό (pró) (governs the genitive)[1] Mycenaean Greek po-ro-, found only in compounds.[2][3]
Etymology
It is inherited from Proto-Hellenic *pró,[1] inherited from Proto-Indo-European *pró (“forward, before”), an adverb and preverb kept in almost every Indo-European language, mostly in compounds.[3][2][1] Beside it stood a form with a long vowel, seen in πρωΐ (prōḯ, “early”).[2][3] The ending is the same as in ἀπό (apó) and ὑπό (hupó).[2]
Cognate with Sanskrit प्र (prá-), Latin pro, Lithuanian pra-, Proto-Germanic *fram and Proto-Celtic *ɸro.[1][3][2] Hittite parā (“forward, forth”) may continue the long or the short form.[2][3] Chantraine and Frisk see a more distant link with παρά (pará), πάρος (páros) and περί (perí), but Chantraine finds the relations impossible to set out clearly.[3][2] Frisk also asks whether πρίν (prín) and πρός (prós) belong here.[2]
Earliest recorded meaning
Homer uses it as an adverb, “forward, forth” and “in front”, and as a preposition with the genitive, “in front of, before”, of place and of time.[4][5][6] In the Iliad a warrior fights or dies “before” his city and his children, that is, in their defence.[5][6]
Semantic evolution
From the local sense “in front of” came the senses of protection (“in defence of, on behalf of”), of time (“earlier than”), of preference (“rather than, above”) and of substitution (“instead of”); LSJ compares the Homeric phrase for dying for one's city with Latin pro patria mori.[5][6] The temporal use grows more frequent after Homer, and later writers put it with numbers: “thirty days before”.[5] Plutarch uses it to render Roman dates, “the day before the Nones” for pridie Nonas.[5][6]
In compounds it marks position in front, as in πρόθυρον (próthuron) and προπύλαια (propúlaia), or first rank and order, as in πρόεδρος (próedros) and προοίμιον (prooímion).[5][3] It also marks standing in another's place, as in πρόξενος (próxenos) and πρόμαντις (prómantis), readiness, as in πρόχειρος (prókheiros) and πρόθυμος (próthumos), and prematureness, as in πρόωρος (próōros).[5][3] With verbs it means “forward”, “in defence”, “in advance” or “in preference”.[5][3] Mycenaean already has it in compounds.[3]
In the Septuagint the phrase “before the face of” renders a Hebrew preposition, and the New Testament has it with a double genitive, “six days before the Passover”.[7][6][8] Medieval Greek kept it as a first element of compounds, as Modern Greek still does; the Modern Greek preposition προ (pro) is a learned word taken from the ancient one.[9][10][11]
