Secret Project (potential names: Iden Man; Itan <>; Iʈen Tava) is spoken high in the Andes in the far future following [redacted].

Phonology
Syllable structure is (C₁)(C₂)V(C₃) word-initially, where C₂ is an approximant, C₁ is not an approximant or rhotic, and C₃ is an occlusive; and CV(C₂) elsewhere, where C₂ is an occlusive.

/ɓ ɗ/ are realized as nasals [m n] before the nasal vowel /ã/ and pre-pausa (most commonly at the end of a word).

/p/ is typically realized as [f] except word-finally.

The front vowels /i e/ are centralized [ɨ ə] before retroflex consonants.

Clause syntax
Word order in a clause is basically VS and AVO, except that all pronouns in a clause cliticize to the front of the verb. Also sometimes weird stuff happens.

Core arguments are mostly unmarked but there's an optional ergative case marker (either that, or marked-absolutive + optional ergative case). Oblique arguments are marked with postpositions.

Noun Phrases
All case markers in a NP cliticize to the end of the NP. Possessors appear before possessed nouns. Nouns are marked for agreement with nouns they modify; this agreement can stack. Relativized NPs are marked for their role in both the subordinate and matrix clause.

Verb Morphology
Verbs are marked for agreement with the subject, most of the time.

Verbs are separated into two parts, the main verb and the preverb, which is a single syllable that normally attaches to the front of the verb but when an aspect auxiliary is present it clitizes to the front of that instead. There are about 15 preverbs, and their assignment to verbs is essentially random although some patterns are observed (all verbs denoting psychological states take the preverb re-, for instance).

There are various voice and valence markers including a causative infix and some sort of (symmetrical?) antipassive. Verbs can incorporate a postposition, which functions like an applicative.

Agreement
There are a large number of agreement classes which are partly phonological and partly semantic. There are several agreement classes with just one member; the agreement marker formally resembles the noun. These include fire, lime, coca leaf, and houses.
