κασίγνητος

Forms

κᾰσίγνητος (kasígnētos) m or f (genitive κᾰσιγνήτου); second declension^[1]

Etymology

It is a compound whose second part is -γνητος (-gnētos, “born”), from the root of γίγνομαι (gígnomai), a term of legitimate, recognised birth.^[2][1][3] Beekes reconstructs Proto-Indo-European *km̥ti-ǵn̥h₁-tos (“born together”), that is, born of the same mother, with the first part from *κατι- (*kati-), the source of καί (kaí);^[4] Thessalian κατίγνειτος (katígneitos) still has the /t/.^[4]

Chantraine finds the first part obscure.^[2] He rejects Wackernagel's idea of a participle of τίκτω (tíktō) that would mark brothers of one womb, as in ἀδελφός (adelphós).^[2] Kuiper compared κατά (katá), and Lejeune, whose solution Chantraine finds plausible, compared Mycenaean Greek ka-si-ko-no “apprentice, companion” and a Hittite preposition meaning “with”.^[2][5] The short form κάσις (kásis) is used in tragedy.^[4]

Earliest recorded meaning

It is found from the Iliad on, meaning a brother, whether of the full or of the half blood, as when Paris is called the brother of Lycaon, Priam's son by another wife.^[3][6]

Semantic evolution

Some Homeric passages show that it could also mean a cousin on the father's side, an old usage that compounds such as αὐτοκασίγνητος (autokasígnētos, “own brother”) and πατροκασίγνητος (patrokasígnētos, “father's brother”) confirm.^[2][4] The feminine κασιγνήτη (kasignḗtē) meant a sister.^[4][6] In the plural it could mean kinsmen in general, and Herodotus uses it of related peoples.^[6]

It is also found in Lesbian, Cypriot and Corcyraean,^[4][2] but elsewhere it became a poetic equivalent of ἀδελφός (adelphós).^[2][4] Sophocles and Euripides use it as an adjective, “of a brother” or “of a sister”.^[6]
