5 Word Building

Two tiers of **hint morphemes** — domain particles and semantic particles — work alongside classifiers and free compounding. Both carry vague, motivated meaning rather than strict definitions: a word built from two particles is a motivated suggestion, not a rigid definition. Speakers interpret combinations by feel. **Monosyllabicity.** Domain and semantic particles target monosyllabic output. When adapting source forms, particles use a **truncation-first strategy** — final syllables may be dropped, clusters reduced, vowels elided. This overrides the general lexical epenthesis rule (which adds a final vowel to source-final consonants other than `n/s/r`).

### 5.1 Overview

Two tiers of **hint morphemes** — domain particles and semantic particles — work alongside classifiers and free compounding. Both carry vague, motivated meaning rather than strict definitions: a word built from two particles is a motivated suggestion, not a rigid definition. Speakers interpret combinations by feel.

> There is no strict priority between the three systems (particles, classifiers, free compounding).

### 5.2 Notes on Particle Form

**Monosyllabicity.** Domain and semantic particles target monosyllabic output. When adapting source forms, particles use a **truncation-first strategy** — final syllables may be dropped, clusters reduced, vowels elided. This overrides the general lexical epenthesis rule (which adds a final vowel to source-final consonants other than `n/s/r`).

Examples: Lat *ventus* → `fen`; Lat *luna* → `run`; Gr *thymos* → `ti`; Gr *skia* → `si`.

**Bisyllabic exceptions.** A particle may be bisyllabic when monosyllabic reduction would produce an ambiguous or phonotactically poor result. Current bisyllabic particles: `aku` (Water, a.ku) and `iro` (Color, i.ro). Such particles are **atomic units** — never decomposed for grammatical analysis.

**Positional rule.** Domain and semantic particles operate as meaningful units only in **compound-initial position**. In compound-final position, a matching syllable is interpreted as a classifier (if in the classifier inventory) or as an ordinary root syllable.

### 5.3 Domain Particles — Tier 1

A domain particle evokes a semantic field's conceptual fingerprint. It may be used as a standalone root or as the first element of a compound.

#### Elements

| Particle | Domain     | Implied feel                           | Source       |
|----------|------------|----------------------------------------|--------------|
| `aku`    | Water      | fluid, serene, dissolving, yielding    | Lat *aqua*   |
| `hi`     | Fire       | intense, consuming, bright, energising | Jp *hi*      |
| `fen`    | Air / wind | light, invisible, pervasive, mobile    | Lat *ventus* |
