Action Namespace

Core Definition

Action frames foreground a sentient, volitional Agent performing an activity, where the activity itself is the primary semantic content. What matters is what the agent does — not any resultant state or change produced. Action frames are typically atelic: there is no inherent endpoint and no required result state.

Formal template:

ACT(Agent, Activity) [± Manner] [± Location] [± Time]

Key participants:

• Agent — the sentient, volitional entity performing the activity (subject position)
• Activity — the action or process being performed

The absence of a result state is the primary contrast with Causative frames. The presence of a volitional agent is the primary contrast with Eventive frames.

Scope

Includes:

• Motion activities: João correu (João ran), Maria nadou (Maria swam)
• Work and labor: João trabalhou (João worked), Maria estudou (Maria studied)
• Performance and expression: João cantou (João sang), Pedro tocou (Pedro played)
• Social interaction: João conversou (João conversed), Maria participou (Maria participated)
• Bodily activities: João comeu (João ate), Maria dormiu (Maria slept)
• Cognitive activities: João pensou (João thought), Maria planejou (Maria planned)

Excludes — see other namespaces:

• Agent causes a change of state in a Patient → Causative (João quebrou o vaso)
• No volitional agent; natural phenomenon → Eventive (Choveu, O vento soprou)
• Affected Theme undergoes state change → Inchoative (O vaso quebrou)
• Agent moves along a directed path to a goal → Transition (João foi para casa)

Important note — transitive actions with non-affected objects: Action frames can take objects, but the object is used as an instrument, not changed as a Patient:

• João tocou o violão → violão unchanged → Action (instrument)
• João quebrou o violão → violão now broken → Causative (Patient)

Subtypes

Telicity: Most Action frames are atelic — compatible with por X tempo (for X time), incompatible with em X tempo (in X time). Activities can be bounded by adding measure phrases (correu um quilômetro), which shifts them toward telic accomplishments, but the namespace focus remains on the activity, not the achieved result.

Diagnostic Tests

Test 1 — Imperative

Can the verb take imperative form directed at a sentient agent?

✓ Corra! (Run!) → ACTION
✓ Trabalhe! (Work!) → ACTION
✗ *Chova! (Rain! — impossible to command nature) → NOT ACTION (Eventive)
✗ *Quebre! (without object — causative needs Patient) → NOT bare ACTION

Test 2 — Purpose clause

Is the activity compatible with para + infinitive (in order to)?

✓ João correu para se exercitar (ran in order to exercise) → ACTION
✓ Maria trabalhou para ganhar dinheiro (worked to earn money) → ACTION

Note: Causative frames also accept purpose clauses, so this test confirms agency but does not distinguish Action from Causative alone.

Test 3 — No result state

Does the event fail to entail a verifiable result state?

✓ João correu → *João está corrido (no result state) → ACTION
✓ Maria cantou → *Maria está cantada (no result state) → ACTION
✗ João quebrou o vaso → O vaso está quebrado (result state exists) → CAUSATIVE

Test 4 — Atelic duration (por X tempo)

Is the activity naturally bounded by por X tempo (for X time) rather than em X tempo (in X time)?

✓ João correu por duas horas → ACTION (atelic)
✓ Maria trabalhou por oito horas → ACTION (atelic)
✗ João quebrou o vaso em um segundo → CAUSATIVE (telic)

Test 5 — Agent can stop and resume

Can the activity be interrupted and resumed without negating its occurrence?

✓ João parou de correr e depois continuou — still counts as having run → ACTION
✗ João parou de quebrar o vaso — punctual, not restartable → CAUSATIVE

Decision Procedure — Action vs Causative

Most Action/Causative misclassifications come from a handful of transitive verbs. Apply these rules in order; the first that fires wins. (This block is identical in the Causative entry — it is the single canonical tie-breaker.)

Rule 0 — Agent gate (run first). If the subject need not be a volitional Agent, the frame is neither Action nor Causative:

• Subject ends up in a new state with no required causer → Inchoative (O Recipiente termina em posse da Massa).
• A property simply holds of an entity → Stative / Attribute (X é adequado para um Propósito).
• A pure speech act / discourse move → Pragmatic.

Rule 1 — Result-state test (the discriminator). After the event, does "X ficou / está ___" hold of an affected entity?

• Yes, verifiable result state → Causative (X is the Patient).
• No → continue.

Rule 2 — Periphrastic causative. Can it be paraphrased with fazer com que … (mude / fique)?

• João fez com que o vaso quebrasse ✓ → Causative.
• ?João fez com que corresse (coercion needed) ✗ → Action.

Rule 3 — Object role. If the frame takes an object, is it changed or merely used?

• Changed (Patient): cortar, limpar, quebrar, abrir, mover → está cortado / limpo / movido → Causative.
• Unaffected (Instrument / content / value): tocar (violão), acessar (mídia), usar (um Valor) → Action.
• Contact without change: esfregar, acariciar, abraçar, beijar, bater, chutar → Action — unless a result is profiled (bateu e quebrou; empurrou a mesa → a mesa ficou no canto) → Causative.

Rule 4 — Purpose ≠ result. Goal phrases (para enfraquecer, destinada a incomodar, para buscar reparação) state intent, not an achieved result. They confirm agency but keep the frame Action.

Rule 5 — Cognition & speech outputs are content, not Patients. A computed Result, an asserted Message, an evaluated Conteúdo is the output of the activity, not an entity changed in state → Action (cognitive / verbal). Exception: when the experiencer himself changes state (Um Evento faz com que o Pensador aceite o Conteúdo — the Thinker comes to accept) → Causative (psychological).

Telicity cross-check. When Rules 1–3 are genuinely tied, fall back to aspect: por X tempo (atelic) → Action; em X tempo with an entailed endpoint → Causative.

Comparison with Adjacent Namespaces

vs. Causative: The critical distinction is the result state. Both require an Agent, but Causative frames produce a change in a Patient that is independently verifiable after the event (o vaso está quebrado). Action frames produce no such result — the activity is complete in itself. Ambiguous cases (e.g., João empurrou Maria): if a result state can be identified, classify as Causative; if the focus is on the activity of pushing, classify as Action.

vs. Eventive: The critical distinction is the volitional agent. Action frames require a sentient, intentional agent and accept imperatives (Corra!). Eventive frames involve natural phenomena or non-agentive occurrences and reject agentive imperatives (✗ Vento, sopre!). Note the asymmetry across boundaries: Action vs. Eventive turns on agency, but Causative vs. Eventive turns on a caused change — a non-agentive natural force that produces a result is Causative (a non-intentional Cause), not Eventive (O vento quebrou a janela).

vs. Inchoative: No direct competition. Action profiles an Agent performing an activity (João correu); Inchoative profiles an affected Theme changing state without an Agent (O vaso quebrou). Different subject roles, different focus.

vs. Transition: Both can involve a moving agent, but Transition profiles the path from source to goal (João foi para casa). Action profiles the manner of activity without requiring a directed path (João correu). When both are present (João correu para casa), path prominence determines the namespace: if the destination is the semantic core, it is Transition; if the manner of motion is the core, it is Action.

vs. Psychological: Cognitive activities (pensar, planejar) can overlap. Classify as Action when the cognitive process is volitional and the agent's performing it is the focus. Classify as Psychological when the mental content or stimulus-response relationship is primary.
