Grammar
Ever since its decipherment, research of Sumerian has been made difficult not only by the lack of any native speakers, but also by the relative sparseness of linguistic data, the apparent lack of a closely related language, and the features of the writing system. Typologically, as mentioned above, Sumerian is classified as an agglutinative, split ergative, and subject-object-verb language. It behaves as a nominative–accusative language in the 1st and 2nd persons of the incomplete tense-aspect, but as ergative–absolutive in most other forms of the indicative mood. Sumerian nouns are organized in two grammatical genders based on animacy: animate and inanimate. Animate nouns include humans, gods, and in some instances the word for "statue". Case is indicated by suffixes on the noun. Noun phrases are right branching with adjectives and modifiers following nouns.Sumerian verbs have a tense-aspect complex, contrasting complete and incomplete actions/states. The two have different conjugations and many have different roots. Verbs also mark mood, voice, polarity, iterativity, and intensity; and agree with subjects and objects in number, person, animacy, and case. Sumerian moods are: indicative, imperative, cohortative, precative/affirmative, prospective aspect/cohortative mood, affirmative/negative-volitive, unrealised-volitive?, negative?, affirmative?, polarative, and are marked by a verbal prefix. The prefixes appear to conflate mood, aspect, and polarity; and their meanings are also affected by the tense-aspect complex. Sumerian voices are: active, and middle or passive. Verbs are marked for three persons: 1st, 2nd, 3rd; in two numbers: singular and plural. Finite verbs have three classes of prefixes: modal prefixes, conjugational prefixes, and pronominal/dimensional prefixes. Modal prefixes confer the above moods on the verb. Conjugational prefixes are thought to confer perhaps venitive/andative, being/action, focus, valency, or voice distinctions on the verb. Pronominal/dimensional prefixes correspond to noun phrases and their cases. Non-finite verbs include participles and relative clause verbs, both formed through nominalisation. Finite verbs take prefixes and suffixes, non-finite verbs only take suffixes. Verbal roots are mostly monosyllabic, though verbal root duplication and suppletion can also occur to indicate plurality. Root duplication can also indicate iterativity or intensity of the verb.
