Introduction
The lexical system of Xha'Ruun is built on a compact root base: ~500 basic roots generate tens of thousands of derived words. The root is monosyllabic (CVC or CV); word formation is agglutinative, through suffixes with transparent semantics.
8.1 Root System
The Xha'Ruun language is based on ~500 roots. Each root is monosyllabic (CVC or CV).
| Root | Meaning | Derivatives |
|---|---|---|
| xha- | thought, mind | xha'ruun (people), xha'ven (truth) |
| khar- | light, star | khar'vex (luminary), kharan (light) |
| the- | soil | thexar (planet), theri (soil) |
| sha- | language, word | sharuu (writing system), shaven (dialect) |
| ruun- | people | ruuna (community), ruunen (society) |
The roots are registered (L-000001–L-000500) and serve as the basis of lexicography. The polysemy of roots is a source of word-formation productivity.
8.2 Word Formation
| Method | Suffix | Example |
|---|---|---|
| Noun | -∅ | khal (life) |
| Adjective | -an | kharan (light) |
| Verb | -en | khalen (to live) |
| Abstraction | -ven | khalven (vitality) |
| Agent | -sha | khalsha (living one) |
| Place | -the | khalthe (habitat) |
The same sound sequence can belong to different morphemes. Derivational elements are distinguished from tense, case and source endings by function and position. For example, -en in the derivational table does not make every word ending in-en a complete present-tense predicate.
8.3 Compound Words
Composition is the second source of vocabulary growth:
- xha + ruun → xha'ruun (people — lit. "mind + people");
- khar + vex → khar'vex (star — "light + home");
- the + xar → thexar (planet — "soil + homeland").
The apostrophe marks the boundary of the components of a compound word.
8.4 Semantic Fields
Roots are grouped into semantic fields:
- Nature — khar (light), the (soil), mor (time), ven (truth);
- Society — sha (language), ruun (people), khal (life), rass (accord);
- Action — khalen (to live), vexen (to build), tharen (to speak).
The fields reflect the cultural priorities of the civilization (→ see [Volume I, Ch.06]).
8.5 Borrowings
The vocabulary includes limited borrowings from the languages of other species:
- Kel'vash — mountain and technical terms;
- Moryn — oceanographic terms.
Borrowings are phonologically adapted (→ see [Volume IV, Ch.02, "Phonology"]).
Chapter Summary

- Word formation is agglutinative; suffix meanings depend on function and position.
- Composition is the second source of vocabulary.
- Semantic fields reflect cultural priorities.
- Limited borrowings from the languages of Kel'vash and Moryn.
