[Seite 128] = τις, einer, nur noch im comp. οὐδαμοί u. in den adv. ἁμῆ, ἁμοῦ, ἁμῶς, ἁμόθεν. Dor. = ἡμέτερος, unser, Hom. Iliad. 6, 414. 8, 178. 10, 448. 13, 96. 16, 830 Od. 11, 166. 481; wie ἡμέτερος, so braucht Homer auch ἁμός von einer Person, das possessiv. des plur. für das des sing.; wie er überhaupt oft den plur. statt des sing. gebraucht. Vgl. Apollon. lex. Hom. 27, 18 Scholl. Iliad. 6, 414 (Herodian.). 8, 178. 13, 96 (Herodian.).
