I've spent the last 5-6 days on E2, so called because of some similarities to E1 (Toilan), mainly in the 9 consonant 4 vowel phonology.
Unmarked clauses are VOS, with fronting used for focus and content question words. Except for quantifiers, modifiers follow nouns, which are marked for one of 5 cases.
WRT subject case, E2 is Active, with the dative case used for subjects of mental-state and perception verbs as well as the nominative and absolutive cases being used for other subjects. However, the affixes are accusative, with the prefix always used for the subject and any suffixes used for objects.
Participles and infinitives are marked for grammatical voice (nominative, absolutive, or dative head/coreference). Finite passives also exist, but are used only for subject omission, since some person-number prefix is needed.
Indicative and contrafactual mood are distinguished in the present and past tenses, but not in the future tense. The aspects are basic (unmarked stative, aoristic, or progressive), specifically progressive, retrospective, habitual, and prospective.
I need to work more on derivation (some are made with prefixes and others with suffixes at present), but the final stem vowel tends to go along with the verb's action type or the noun's internal role.
The vocabulary is around 20 words, not counting function words.
