1. Aeolic has recessive ( cross159) accent in all words except prepositions and conjunctions. Thus, σόφος, Ζεῦς, i.e. Ζέὺς, αὖτος, λίπειν (= λιπεῖν), λίποντος (= λιπόντος), ἄμμες (= ἡμεῖς).
2. Doric regarded final -οι ( cross169) as long (ἀνθρώποι), and probably -αι in nouns (χώραι); made paroxytones the 3 pl. act. of the past tenses (ἐφέρον, ἐλύ_σαν) and such words as παίδες, γυναίκες, πτώκας; made perispomena the gen. masc. pl. of pronouns (τουτῶν, ἀλλῶν) and the gen. fem. pl. of adj. in -ος (ἀμφοτερᾶν). The substitution, in the accus. pl., of -ας and -ος for -α_ς and -ους, caused no change in the accent (πά_σας, ἀμπέλος).
