Pronunciation
Forms
σός (sós) m (feminine σή, neuter σόν); first/second declension[1] Epic, Doric and Aeolic τεός (teós), Boeotian τιός (tiós); epic genitive σοῖο.[2][3][4]
Etymology
It is inherited from Proto-Indo-European *twós (“your”), the possessive formed from the stem of the pronoun of the second person, σύ (sú).[1][3] Beekes derives it from *τϝός (*twós), and the Doric, Aeolic and Homeric τεός (teós) from *τεϝός (*tewós), both continuing Indo-European *t(e)wo-, and Boeotian has τιός (tiós).[3] The initial /s/ comes from the sequence /tw/, as in the accusative σέ (sé) from *twe.[3]
Cognate with Sanskrit त्व (tvá), Old Armenian քո (kʻo), Latin tuus and Lithuanian tãvas.[1][3][5]
Earliest recorded meaning
It is found from the Iliad on, meaning “your” of one person, with or without the article, beside the epic τεός (teós); the Odyssey has the epic genitive σοῖο.[6][2][7]
Semantic evolution
In Attic it is used freely with the article, as in τὸ σὸν κάρα “your head” in Aeschylus, but never when it is the predicate, as in Sophocles' πάτερ, σός εἰμι, “father, I am yours”.[2] It can also look towards the person addressed, the sense of an objective genitive: Homer's σὸς πόθος is the longing for you.[4]
Used as a noun, the masculine refers to a person's husband (in Euripides), the plural οἱ σοί to one's family, friends or followers (Herodotus, Sophocles, Euripides), and the neuter to one's part, interest or affairs.[4][2] In the New Testament it marks emphasis or contrast, as in the question about the beam “in your own eye”.[8]
The vernacular Greek of 1100–1669 still used it, and it survives in modern dialects.[9]
