2. Ionic has η for the α_ of Attic even after ε, ι, and ρ; thus, γενεή, οἰκίη, ἀγορή, μοίρης, μοίρῃ (nom. μοῖρα^), νεηνίης. Thus, ἀγορή, -ῆς, -ῇ, -ήν; νεηνίης, -ου, -ῃ, -ην. But Hom. has θεά_ goddess, Ἑρμεία_ς Hermes.

3. The dialects admit -α^ in the nom. sing. less often than does Attic. Thus, Ionic πρύμνη stern, κνί_ση savour (Att. πρύμνα, κνῖσα), Dor. τόλμα_ daring. Ionic has η for α^ in the abstracts in -είη, -οίη (ἀληθείη truth, εὐνοίη good-will). Hom. has νύμφα^ oh maiden from νύμφη.

4. Nom. sing. masc.—Hom. has -τα for -της in ἱππότα horseman, ἱππηλάτα driver of horses, νεφεληγερέτα cloud-collector, κυ_ανοχαῖτα dark-haired; and, with recessive accent, μητίετα counsellor. So in the adj. εὐρύοπα far-sounding. Cp. Lat. poeta, scriba.

5. Gen. sing. masc.—(a) -α_ο, the original form from α_-（ι）ο, is used by Hom. (Ἀτρείδα_ο). It contracts in Aeolic and Doric to -α_ (Ἀτρείδα_).

(b) -εω, from ηο (= α_ο) by 34, is also used by Hom., who makes it a single syllable by synizesis (60), as in Ἀτρείδεω. Hdt. has -εω, as πολί_τεω (163 a).

(c) -ω in Hom. after a vowel, Βορέω (nom. Βορέης).

6. Accus. sing. masc.—In proper names Hdt. often has -εα borrowed from ς stems (264), as Μιλτιάδεα for Μιλτιάδη-ν.

7. Dual.—Hom. has the nom. dual of masculines only. In the gen. and dat. Hom. has -αιν and also -αιιν.

8. Gen. plur.—(a) -ά_ων, the original form, occurs in Hom. (μουσά_ων, ἀγορά_ων). In Aeolic and Doric -ά_ων contracts to (b) -ᾶν (ἀγορᾶν). The Doric -ᾶν is found also in the choral songs of the drama (πετρᾶν rocks). (c) -έων, the Ionic form, appears in Homer, who usually makes it a single syllable by synizesis (60) as in βουλέωνν, from βουλή plan. -έων is from -ήων, Ionic for -ά_ων. (d) -ῶν in Hom. generally after vowels (κλισιῶν, from κλισίη hut).

9. Dat. plur.: -ῃσι（ν), -ῃς, generally before vowels, and (rarely) -αις in Hom. Ionic has -ῃσι, Aeolic -αισι（ν), -αις, Doric -αις.

10. Accus. plur.: -ανς, -α^ς, α_ς in various Doric dialects, -αις in Aeolic.
