Inchoative Namespace
Core Definition
Inchoative frames foreground an affected entity (Theme) undergoing a transition into a new state. The primary semantic content is the achievement of a resultant state — not who caused the change, nor the path of change. Inchoatives are inherently telic: the resultant state is the built-in endpoint of the event.
Formal template:
BECOME(State(Theme))
Key participants:
- Theme — the entity that undergoes the change (subject position)
- Result — the new state achieved (implied by the verb)
Causation may be conceptually present but is not profiled. This is the core contrast with Causative frames, which use the same verbs but with an Agent in subject position.
Scope
Includes:
- Physical state changes: O vaso quebrou (The vase broke), O gelo derreteu (The ice melted)
- Property / scalar changes: A situação melhorou (The situation improved), O produto encareceu (The product got expensive)
- Spatial / configurational changes: A porta abriu (The door opened), O leque fechou (The fan closed)
- Condition / status changes: João adoeceu (João became sick), A fruta amadureceu (The fruit ripened)
- Existential changes: O problema surgiu (The problem appeared), A empresa desapareceu (The company disappeared)
Excludes — see other namespaces:
- Agent causing the change → Causative (João quebrou o vaso)
- Volitional agent activity without state change → Action (João correu)
- Path / goal-oriented movement → Transition (João foi para casa)
- Static properties → Stative (O vaso é frágil)
Critical relationship to Causative — the alternation: Inchoative and Causative are two perspectives on the same class of events:
- João abriu a porta → Causative (Agent in subject; causation profiled)
- A porta abriu → Inchoative (Theme in subject; causation backgrounded)
Subtypes
By change type:
| Subtype | Definition | Example LUs |
|---|---|---|
| Physical | Change in structural integrity or material state | quebrar, derreter, enferrujar, apodrecer, evaporar |
| Property / Scalar | Change along a scale (temperature, size, quality) | melhorar, crescer, esfriar, aumentar, diminuir |
| Configurational | Change in spatial position or configuration | abrir, fechar, subir, desabrochar |
| Condition / Status | Change in biological, social, or abstract state | adoecer, amadurecer, enriquecer, aposentar-se |
| Existential | Entity comes into or ceases to exist | surgir, aparecer, morrer, desaparecer, extinguir-se |
Gradability:
| Type | Features | Key test |
|---|---|---|
| Punctual (achievement) | Instantaneous change; no internal phases | Incompatible with progressive; em X tempo natural |
| Gradual (accomplishment) | Unfolds toward endpoint over time | Compatible with progressive; both em and por X tempo natural |
quebrar is typically punctual (O vaso quebrou — instant); amadurecer is gradual (A fruta está amadurecendo).
Causative alternation: Most inchoatives alternate with a transitive causative. Some do not:
- Alternating: abrir, quebrar, derreter, secar — the same change can be caused externally
- Non-alternating (intransitive only): morrer, surgir, florescer — change is inherently spontaneous; expressing a causer requires periphrasis (fazer com que)
Diagnostic Tests
Test 1 — Result state (estar + participle)
Does the frame entail a specific resultant state, verifiable after the event?
✓ O vaso quebrou → O vaso está quebrado → INCHOATIVE
✓ A porta abriu → A porta está aberta → INCHOATIVE
✗ João correu → *João está corrido (no stable result state) → NOT INCHOATIVE
Test 2 — Theme in subject, no Agent profiled
Is the affected entity in subject position, with no volitional Agent expressed?
✓ O gelo derreteu (Theme = gelo) → INCHOATIVE
✗ João derreteu o gelo (Agent = João) → CAUSATIVE
Test 3 — BECOME decomposition
Can the verb's meaning be read as entity comes to be in state X?
✓ quebrar = BECOME(broken) → INCHOATIVE
✓ adoecer = BECOME(sick) → INCHOATIVE
✗ correr ≠ BECOME(state) → NOT INCHOATIVE (Activity)
Test 4 — Causative-inchoative alternation
Does the frame have a transitive (causative) counterpart with the same verb?
✓ A porta abriu ↔ João abriu a porta → INCHOATIVE / CAUSATIVE pair
✓ O gelo derreteu ↔ O sol derreteu o gelo → INCHOATIVE / CAUSATIVE pair
✗ O problema surgiu ↔ *João surgiu o problema → NON-ALTERNATING inchoative (still Inchoative)
Test 5 — Telicity
Does the event have a natural endpoint (bounded)?
✓ A água congelou em dez minutos (em X tempo — bounded) → INCHOATIVE
✗ A água fluiu por dez minutos (por X tempo — unbounded) → NOT INCHOATIVE (Eventive / Activity)
Comparison with Adjacent Namespaces
| Feature | Inchoative | Causative | Eventive | Action | Stative |
|---|---|---|---|---|---|
| Agent / Cause profiled | No | Yes | No | Yes | No |
| Result state as focus | Yes | Yes | No | No | Yes |
| Telic (inherent endpoint) | Yes | Yes | Varies | No | N/A |
| Dynamic (change occurs) | Yes | Yes | Yes | Yes | No |
| Theme in subject | Yes | No | Varies | No | Yes |
vs. Causative: Same verb, same event, different perspective. Causative puts the Agent in subject position and profiles the act of causing (João quebrou o vaso). Inchoative puts the Theme in subject position and profiles the state change (O vaso quebrou). The resultant state is identical in both; namespace membership depends on which participant is foregrounded.
vs. Eventive: Both can profile a Theme changing without an Agent, but the focus differs. Inchoative foregrounds the resultant state (O vaso está quebrado — the broken state is what matters). Eventive foregrounds the occurrence of the event as a process. The same sentence (O gelo derreteu) can lean Inchoative (if the liquid state is primary) or Eventive (if the melting process is primary); context disambiguates.
vs. Action: Actions profile an Agent performing an activity with no obligatory result state; inchoatives profile a Theme changing state with no Agent. Actions are atelic; inchoatives are telic.
vs. Stative: Statives describe a state that already holds (O vaso é frágil). Inchoatives describe the transition into a state (O vaso quebrou). The result state of an inchoative (O vaso está quebrado) resembles a stative description, but implies the prior change event.
vs. Transition: Transition frames profile movement along a path toward a goal (João foi para casa). Inchoative configurational changes focus on the achieved spatial configuration, not the path: A porta abriu (door is now open, path irrelevant) vs. O balão subiu até o teto (Transition — path to goal is primary).
