Volume IV: Language — Chapter 3: Grammar: Overview
"The Xha'Ruun language is agglutinative. Each morpheme is a building block from which utterances are constructed. 14 cases, 4 tenses, 3 numbers, 4 types of evidentiality — precision that still needs context." — Academician of Grammar, Tor-Ven

Introduction
Xha’Ruun is predominantly agglutinative. Explicit number, case, tense and source marking helps analysis; polysemy and contextual ambiguity remain. Nouns have stem–number–case structure; source marking belongs to the finite declarative predicate.
3.1 Typological Characteristics
| Parameter | Value |
|---|---|
| Type | Agglutinative, suffixal |
| Word order | SOV (subject-object-verb) |
| Cases | 14 |
| Numbers | 3 (singular, dual, plural) |
| Gender | None |
| Evidentiality | Required in finite declarative predicates (4 types) |
| Tense | 3 + 1 (past, present, future + gnomic) |
Agglutination is the main mode of inflection. The three numbers are singular, dual and plural: grammatical quantities, not biological sexes. There is no grammatical gender.
3.2 Word Structure
Noun form and following predicate
- Stem-(root)
- number_suffix
- case_suffix
- Then a predicate with source marking
Example noun: xha’ruun-ak-sha, “peoples” as transitive agent (A). The predicate marks the source of the assertion; the noun does not take an extra evidential suffix.
Noun suffix order is stem → number → case. Sound-alike endings are distinguished by position and function: dative -ven and source -ven occupy different parts of the sentence.
3.3 Case System
The 14 cases are divided into groups (→ see [Volume IV, Ch.04, "14 Cases"]):
- Grammatical: nominative (S), ergative (A), accusative (P), dative;
- Spatial: inessive, superessive, ablative, allative;
- Other: genitive, instrumental, comitative, translative, essive, terminative;
- A temporal limit uses the terminative; it does not add another group of cases.
3.4 Evidentiality
In a finite declarative predicate, the speaker indicates the source of information (→ see [Volume IV, Ch.06, "Evidentiality"]):
- Direct (saw/heard);
- Inferential (conclusion);
- Reportative (from others' words);
- Quotative (direct speech).
3.5 Syntax
The SOV order is supplemented by:
- Agglutinative postpositions (case suffixes perform their role);
- Free order within the clause with marked cases;
- Complex sentences through suffixal conjunctions and evidentiality.
Chapter Summary
- Agglutinative suffixal system, SOV order.
- 14 cases, 3 numbers, absence of gender.
- Four source types in finite declarative predicates.
- Noun structure: stem + number + case. The predicate marks source.
- Morphemes are segmentable — the word is transparent for analysis.
