πατήρ, a father, and μήτηρ, a mother, have πατρός and μητρός in genitive, and πατρί and μητρί in dative; but the objective is in the regular form with the short penult πατέρα. θυγάτηρ, a daughter, follows the same rule, ἀνήρ has ἀνδρός, ἀνδρί, ἄνδρα.
βασιλεύς, a king, and ἱερεύς, a priest, have the genitive in έως, and the dative in εῖ, like πόλις, but the objective is έα. βοῦς, an ox, has βοός, βοί, and βοῦν.
γυνή, a woman, has genitive and dative -αικός, -αικί, and objective -αῖκα.
