Ancient Greek κῆδος is an attested neuter noun whose lexical record spans care or concern, anxiety and grief, troubles, mourning and funeral rites, an object of care, and connection by marriage. LSJ documents the Doric variant κᾶδος, Homeric plural forms such as κήδεα or elided κήδεʼ, an Aeschylean play between Helen as an object of care and marriage connection, and a warning that some marriage-based readings of Homeric passages are wrong. Comparative sources place the noun beneath a proposed *ḱh₂d-es- formation and *ḱeh₂d- base alongside Celtic and Germanic material, but the semantic unity of care, grief, battle, hostility, pursuit, and hate remains disputed. The dossier preserves the Greek semantic network, the proposed ancestry, and the explicit boundary as separate claim layers.
