Transition Namespace
Core Definition
Transition frames foreground a Theme moving along a directed path — from a Source, through a trajectory, to a Goal. The primary semantic content is the traversal itself: the movement through space or change along an abstract dimension, not merely the starting or ending point. Transitions are typically telic: the path leads toward an inherent endpoint.
Formal template:
MOVE(Theme, FROM(Source), TO(Goal), ALONG(Path), [via_Manner])
Key participants:
- Theme — the entity that moves or changes (subject position)
- Source — starting point or state (optional; often backgrounded)
- Goal — destination or target state (often obligatory or foregrounded)
- Path — the trajectory connecting Source to Goal (may be elaborated or schematic)
- Manner — how motion occurs (always expressed as an adjunct in Portuguese, never in the verb root)
Scope
Includes:
- Physical motion: João foi para casa (João went home), Maria chegou ao Brasil (Maria arrived in Brazil)
- Path-crossing: João saiu da sala (João left the room), Maria atravessou a rua (Maria crossed the street)
- Possession transfer: A propriedade passou de João para Maria (The property passed from João to Maria)
- Abstract state transitions: João passou de estudante a professor (João went from student to professor)
- Scalar change with endpoints: A temperatura subiu de 20° para 30°
Excludes — see other namespaces:
- Volitional activity with no directed path → Action (João correu)
- Theme achieves a result state; path not profiled → Inchoative (A porta abriu)
- State holds without change → Stative (João está em casa)
- Mental or perceptual event → Psychological (João percebeu o erro)
Critical boundary — manner verbs: Portuguese is verb-framed: path is encoded in the verb root, manner is expressed as a separate adjunct (saiu correndo, not correu para fora). This has direct classification consequences:
- Manner verb + Goal/Source PP → Transition (João correu para casa)
- Manner verb alone, no path expression → Action (João correu)
Subtypes
By path profiling:
| Subtype | Features | Example LUs |
|---|---|---|
| Goal-profiling | Goal is obligatory or strongly preferred; Source backgrounded | ir, vir, chegar, entrar |
| Source-profiling | Source is obligatory or strongly preferred; Goal backgrounded | sair, partir, emergir |
| Path-profiling | Path/trajectory is obligatory; Source and Goal may be unspecified | passar, atravessar, percorrer |
| Source-Goal | Both endpoints relevant; path less emphasized | mudar, transferir, passar (de-para) |
By domain:
| Domain | Definition | Example LUs |
|---|---|---|
| Physical/Spatial | Literal movement through space | ir, sair, chegar, subir, descer, entrar |
| Possession transfer | Change of ownership or control | dar, passar, transferir, enviar |
| State transition | Movement along an abstract dimension | mudar, tornar-se, virar, transformar-se |
| Abstract | Metaphorical extension (information, category) | transmitir, reclassificar, passar de X a Y |
By aspect:
| Type | Features | Key test |
|---|---|---|
| Durative (accomplishment) | Unfolds over measurable time toward endpoint | Compatible with progressive and em X tempo |
| Punctual (achievement) | Instantaneous or near-instantaneous | Point-in-time modification; progressive coerced |
Viajar para o Rio is durative (João está viajando); chegar ao Rio is punctual (João chegou às 5h).
Diagnostic Tests
Test 1 — Path expression (FROM / TO / THROUGH)
Does the frame accept or require Source, Goal, or Path arguments?
✓ João foi DE casa PARA o trabalho → Source + Goal → TRANSITION
✓ Maria passou PELA praça → Path → TRANSITION
✗ João correu (no Goal, no Source, no Path) → NOT TRANSITION (Action)
Test 2 — MOVE decomposition
Can the verb's meaning be read as entity moves from X to Y along a path?
✓ chegar = MOVE(Theme, TO(Goal)) → TRANSITION
✓ sair = MOVE(Theme, FROM(Source)) → TRANSITION
✗ existir ≠ MOVE(...) → NOT TRANSITION (Stative)
✗ correr ≠ MOVE(...) (without path expression) → NOT TRANSITION (Action)
Test 3 — Theme mobility
Does the Theme change location or state as a result of the event?
✓ João viajou para o Rio (João changed location) → TRANSITION
✗ João permaneceu em casa (João did not change location) → STATIVE
Test 4 — Directionality
Does the frame encode inherent direction — toward a Goal or away from a Source?
✓ entrar (inward direction, toward Goal) → TRANSITION
✓ subir (upward direction) → TRANSITION
✓ sair (outward direction, away from Source) → TRANSITION
✗ estar (no direction encoded) → STATIVE
Test 5 — Telicity
Does the frame have an inherent endpoint toward which the Theme moves?
✓ chegar (arrival = inherent endpoint required) → TELIC TRANSITION
✓ ir para casa (home = destination endpoint) → TELIC TRANSITION
? João correu por uma hora (no endpoint) → ACTION (manner activity, not transition)
Comparison with Adjacent Namespaces
| Feature | Transition | Inchoative | Action | Psychological | Stative |
|---|---|---|---|---|---|
| Path / trajectory profiled | Yes | No | No | No | No |
| Theme changes location or state | Yes | Yes | No | No | No |
| Agent required | No | No | Yes | No | No |
| Result state as focus | No | Yes | No | No | Yes |
| Telic (inherent endpoint) | Yes | Yes | No | Varies | No |
vs. Inchoative: Both involve a Theme undergoing change, but the focus differs. Inchoative foregrounds the resultant state (A porta está aberta — the open state matters). Transition foregrounds the path from X to Y (João foi para casa — the journey is the semantic core). When the endpoint state is primary, classify as Inchoative; when the path or directed movement is primary, classify as Transition.
vs. Action: Both can involve a moving agent, but Action profiles the manner of activity without a directed path (João correu — atelic, no destination). Transition profiles the directed movement toward a goal (João correu para casa — telic, destination required). The presence of a Goal, Source, or Path expression is the decisive test: if present, Transition; if absent, Action.
vs. Psychological: Abstract or metaphorical uses (João passou da ignorância ao conhecimento) may look Psychological because they involve a sentient subject undergoing change. Classify as Transition when the Source-Path-Goal schema is prominent — when the sentence explicitly frames the change as movement from one state to another along a dimension. Classify as Psychological when the mental or perceptual content is primary and spatial metaphor is not foregrounded.
vs. Stative: Stative frames describe a state that already holds (João está em casa — he is located there, no movement). Transition frames describe movement into or through a location or state. A locational stative (João está em casa) and a transition toward the same location (João foi para casa) are clearly distinct: one describes the state of being, the other the path of arrival.
