Compounds
Compound words are the engine of Tonesu vocabulary. Almost every word in the language is a compound — a sequence of primitive roots that together name a concept.
Notation in this page: Written Tonesu has no hyphens —
toliis the word. The analytic breakdownto-li(hyphenated) appears in parentheses or labeled as parse to show structure.
The basic rule: right-branching
In a compound, the rightmost root is the head — it determines the grammatical class and general meaning. Everything to its left modifies it.
toli (to-li: to = knowledge, li = person) → knower, scholar
tosumu (to-su-mu: to-su = organised knowledge, mu = device) → library, database
The parse is right-branching by default: in a chain A-B-C, the structure is A modifying [B-C].
tosumu (to-su-mu) → [to + [su + mu]] → knowledge + [structure + device] → knowledge-organisation device
Reading a new compound
Because Tonesu compounds are compositional, you can decode them left to right:
- Identify each root (see Primitives)
- Find the head (rightmost root)
- Let the left roots narrow the meaning
Practice:
rakimu (ra-ki-mu) — ra = energy, ki = motion/change, mu = device → energy-change device → engine, motor, generator
nera (ne-ra) — ne = relation, ra = energy → energetic relation → resonance, energetic coupling
The juncture marker '
Long compounds are still right-branching by default. When a left subgroup should be read as a unit before combining with the rest, use ' to mark its left boundary:
pawi'kasu (pa-wi'ka-su) = [pa-wi] + [ka-su] → destination-place of structured-action → shrine, temple
Without the ', the parse would be pa + [wi + [ka + su]] — which reads differently. The apostrophe makes the intended grouping visible.
' is not just a readability tool — it can be required for correctness. Consider a color modifier attached to a kind-term compound:
kerzoseso → (wrong) ker modifies only the final root so
ker'zoseso → (right) ker modifies {zoseso} as a whole kind-term
Without ', the color binds to the wrong element. With it, the entire organism class is qualified.
~ (the approximation mark) can follow ' immediately to hedge just the subcompound:
ker'zoseso → the red canid-pack kind
ker'~zoseso → the red something-like-canid-pack kind (uncertain about the base class)
Derivational suffixes
Some roots act as productive suffixes that specify the grammatical role of a compound:
| Suffix | Role | Written example | Parse |
|---|---|---|---|
-li |
agent (person who does X) | toli |
to-li |
-mu |
device (thing that does X) | rakimu |
ra-ki-mu |
-pa |
place (where X happens) | wikapa |
wi-ka-pa |
-ki |
entering a state (inchoative) | neraki |
ne-ra-ki |
-su |
structural result | wikasu |
wi-ka-su |
Stacking order: root → semantic modifier → role suffix.
tokimu (to-ki-mu) = toki (knowledge-change) + -mu (device) → computer
tokili (to-ki-li) = toki (knowledge-change) + -li (agent) → learner
Negation prefix no-
Prefixing no- to a root or compound negates or reverses it:
no- = absence, negation, lack of
nodema (no-de-ma) = no + decay + matter → salt, preservative matter
nonefe (no-ne-fe) = no + relation + boundary → no dependency, free-standing
Depth and complexity
Most compounds are 2–4 roots. Longer compounds are valid but should use ' grouping to keep the parse clear at depth 5 or more. If a compound feels unwieldy, it is usually better expressed as a multi-word phrase.
Three stages of a compound's life
- Compositional — you read it and the meaning falls out directly
senoto (se-no-to) = perception + absence + knowledge → a signal without an interpretive model
- Algebraic default — a recognized operator pattern makes the reading predictable across a whole class
X-fe → boundary / limit of X
tofe (to-fe) → epistemic boundary (the line between knowledge states)
wife (wi-fe) → intentional limit (ethical constraint, policy bound)
tife (ti-fe) → temporal deadline
- Registry-stabilised — corpus use has confirmed a specific narrower reading
rasu (ra-su) — algebraic reading: energy structure · registered reading: star (stable in astronomy contexts)
Most of the words in the word list are at stage 3. Many useful compounds never need registration — their meaning falls directly out of the structure every time.

These patterns apply across any compatible root, generating whole families of words with the same logic.
