Eventive Namespace

Core Definition

Eventive frames profile dynamic occurrences where the event itself is the primary semantic content. Something happens — the happening is what matters most. Participants are optional, backgrounded, or semantically underspecified; no volitional Agent is required or profiled. This namespace serves as a residual category for dynamic events that don't fit the more specialized namespaces (Agentive, Change, Transition, Process, Undergoing, Experiential).

Unit / punctual view — the contrast with Process. Eventive frames profile an occurrence as a single, bounded unit — one happening, taken as a whole without decomposition into sub-events. The moment the profiled content is a process as a whole, extended and composed of many sub-events (a life, a history, an ongoing institutional or biological process), the frame belongs to @process, not here. Eventive is the unit/punctual view; Process is the whole-process view. The two form the Eventive ↔ Process perspective pair (one Event, two Situations).

Formal template:

OCCUR(Event) [± Theme] [± Location] [± Time]

Scope

Includes:

• Natural/meteorological phenomena: chover (rain), nevar (snow), vento soprar (wind blow)
• Geological and physical processes: terremoto (earthquake), erosão (erosion), erupção (eruption)
• Biological processes (non-volitional): crescer (grow), amadurecer (ripen), apodrecer (rot)
• Physical/chemical processes: evaporar (evaporate), oxidar (rust), queimar (burn)
• Spontaneous occurrences: acontecer (happen), surgir (arise/appear)
• Existence and its cessation: existir (exist), surgir (appear), desaparecer (disappear)

Excludes — see other namespaces:

• Volitional agent activities → Agentive (João correu — João ran)
• Any caused result — including by a natural force → Agentive (João quebrou o vaso; O vento quebrou a janela)
• Result-state-focused change with no causer profiled → Change (O vaso quebrou — The vase broke)
• An affected Patient undergoing an externally-instigated event (not a bare occurrence with a generic Theme) → Undergoing (A colheita sofreu com a geada)
• Path/goal-oriented motion → Transition
• Occurrence profiled as a whole process composed of many sub-events → Process (envelhecer as a life process, História)
• Static properties and relations → Stative

Critical boundary — a caused result is never Eventive: Eventive covers bare occurrences with no caused change. The moment a causer (of any kind) acts on a Patient to produce a result, the frame is Agentive, because a natural force is a non-intentional Cause — not a reason to choose Eventive:

• O vento soprou (the wind blew) → Eventive (no Patient, no result — a pure occurrence)
• O vento quebrou a janela (wind broke the window) → Agentive (o vento = Cause; janela = Patient; result profiled)
• A janela quebrou (the window broke) → Change (affected entity in subject, causer unprofiled)

Subtypes

Telicity: Most eventive frames can be classified by a single test:

• "por X tempo" (for X time) compatible → atelic Activity (O rio fluiu por horas)
• "em X tempo" (in X time) compatible → telic Accomplishment (A fruta amadureceu em duas semanas)

The same frame can shift depending on context: A madeira queimou por horas (atelic — ongoing burning) vs. A madeira queimou em duas horas (telic — burned down completely).

Participant flexibility: A defining property across all subtypes:

• Absent: Choveu (It rained — zero participants)
• Optional: Houve um terremoto [no Chile] (Location not required)
• Underspecified: A água flui (Theme present but role is generic — not Agent, not Patient)

Characteristic signature

The residual namespace: a frame is classified here when it profiles a dynamic occurrence but fits no more specialised namespace. It covers occurrences with no caused change profiled — natural phenomena (choveu, o vento soprou), spontaneous processes (a fruta amadureceu), disease as process or progression, and existence (surgir, desaparecer). Choose Eventive only when nothing better fits.

A natural force that produces a result is not Eventive. Membership turns on the absence of a caused change, never on the nature of the causer. A natural/physical force acting on a Patient to bring about a Result is a non-Sentient Cause, so o vento quebrou a janela is Agentive, not here — exactly as João quebrou a janela is. The Sentient vs. non-Sentient contrast only splits Agent from Cause inside Agentive; it does not gate Agentive vs. Eventive. What lands in Eventive is the intransitive counterpart with no causer profiled (o vento soprou, a janela quebrou-as-occurrence).

Multiple participants in Eventive. Eventive's signature is deliberately thin — Event plus an optional, generic Theme. Real eventive frames often have more than one participant, which raises two recurring questions; the answers follow from §1:

• Do not group two distinct participants under the same Theme. A qualia role is one role slot; treating two FEs as the same Theme asserts they play the same generic role and erases the distinction the qualia vocabulary exists to record. Reserve co-typing for genuinely co-typed participants (a reciprocal pair, X e Y colidiram).
• Record a sharper participant on a sharper CONSTITUTIVE sub-role, not as a second Theme. In §1, Instrument, Source, Path, Part, and Material are all is_a Theme — refinements of the generic participant. Assign the sub-role that fits; use bare Theme only when there is no sharper characterization.
• Coverage is partial by design. Genuinely peripheral participants need not be characterized at all; their being left out is itself informative.

A participant that is clearly affected and reaches a result state is a smell: that Patient + Result signature is the Agentive/Change signature, not Eventive's. Such a frame is a candidate for the Change ↔ Eventive perspective pair (§4), or — if a causer is profiled in subject position — for Agentive outright. (Recall that, under the boundary above, a natural-force causer makes the frame Agentive, not Eventive.)

Diagnostic Tests

These tests are meant to be applied to a frame's core participants and semantic structure to determine whether it belongs in the Eventive namespace.

Test 1 — No Agent required

Can the core event occur without specifying a volitional agent?

✓ Choveu (It rained — agent impossible) → EVENTIVE
✗ João matou (agent obligatory) → NOT EVENTIVE

Test 2 — Agent incompatibility

Is adding an intentional human agent as subject odd or ungrammatical?

✓ A rocha erodiu (The rock eroded — no agent) → EVENTIVE
✗ João construiu a casa (agent required) → NOT EVENTIVE (Agentive)

Test 3 — Spontaneity

Is the event conceptualized as arising naturally, without external instigation?

✓ A fruta amadureceu (ripened — internal biological process) → EVENTIVE
✗ João amadureceu a fruta artificialmente → CAUSATIVE (if acceptable)

Test 4 — Middle voice se

Does the frame naturally accept reflexive se to signal spontaneity?

✓ O problema se resolveu (The problem resolved itself) → EVENTIVE
✗ *João se construiu uma casa (ungrammatical middle) → NOT EVENTIVE

Test 5 — Impersonal or existential construction

Can the frame appear impersonally or with haver / ocorrer?

✓ Choveu muito / Houve uma tempestade → EVENTIVE
✗ *Houve João matando Pedro (unnatural) → NOT EVENTIVE

Test 6 — Participant minimality

Can the frame occur with no or minimal specified participants?

✓ Nevou (It snowed — no participants) → EVENTIVE
✗ João deu (incomplete — requires recipient) → NOT EVENTIVE

Test 7 — Generic Theme role

When participants are present, is their role semantically general (not clearly Agent or Patient)?

✓ A água flui (Water flows — generic Theme, not affected, not causing) → EVENTIVE
✗ João quebrou o vaso (Agent + Patient well-specified) → CAUSATIVE
