Ancient Greek grammar Ancient Greek grammar Ancient Greek grammar is morphologically complex and preserves several features of Proto-Indo-European morphology. Nouns, adjectives, pronouns, articles, numerals and especially verbs are all highly inflected. Another complication of Greek grammar is that different Greek authors wrote in different dialects, all of which have slightly different grammatical forms (see Ancient Greek dialects). For example, the history of Herodotus and medical works of Hippocrates are written in Ionic, the poems of Sappho in Aeolic, and the odes of Pindar in Doric; the poems of Homer are written in a mixed dialect, mostly Ionic, with many archaic and poetic forms.
Ancient Greek phonology present in English or Modern Greek, such as a three-way distinction between voiced, voiceless, and aspirated stops (such as , as in English "bot, spot, pot"); a distinction between single and double consonants and short and long vowels in most positions in a word; and a word accent that involved pitch. Koine Greek, the variety of Greek used after the conquests of Alexander the Great in the fourth century BC, is sometimes included in Ancient Greek, but its pronunciation is described in Koine Greek phonology.
