Aspect × Temporal Connective Interaction Bridge #

@cite{alstott-aravind-2026} @cite{moens-steedman-1988} @cite{rett-2020}

Connects three layers:

  1. Fragment field: TemporalExprEntry.embeddedTelicityEffect : Bool
  2. Theory: VendlerClass.telicity, INCHOAT, COMPLET operators
  3. Data: AspectInteraction judgments from @cite{moens-steedman-1988}

What This File Proves #

  1. embeddedTelicityEffect = true holds exactly for connectives whose truth conditions change depending on the Vendler class of the embedded clause (before, after). This is because they reference boundary points (onset/telos) that depend on aspect.

  2. embeddedTelicityEffect = false holds for connectives that use overlap or containment semantics (while, when, until, since), which are insensitive to the internal temporal structure of the embedded clause.

  3. The triggeredCoercion field is grounded in the theory's INCHOAT and COMPLET operators: INCHOAT extracts the onset point (= CoSType.inception), COMPLET extracts the telos (= CoSType.cessation).

  4. The satisfiesDurativeRestriction predicate (from Data) coincides with VendlerClass.toProfile.isHomogeneous: exactly states and activities satisfy the durative requirement for until and since main clauses.

The Explanatory Chain #

VendlerClass.telicity TemporalExprEntry.embeddedTelicityEffect
.telic /.atelic ──────────► true (before, after: reading depends on telicity)
                                false (while, when, until, since: insensitive)

VendlerClass.duration *until*/*since* selectional restriction
.durative ─────────────────► satisfiesDurativeRestriction = true (OK)
.punctual ─────────────────► satisfiesDurativeRestriction = false (BAD)

INCHOAT / COMPLET Fragment.triggeredCoercion
  INCHOAT(stative) = onset ───► "INCHOAT" for within_, after_ (coerced)
  COMPLET(telic) = telos ─────► "COMPLET" for at_punct, before_ (coerced)

embeddedTelicityEffect = true holds exactly for connectives that reference boundary points (onset/telos) of the embedded clause. These are before and after: their truth conditions change depending on whether the embedded clause is telic or atelic, because:

  • Telic → natural endpoint exists → COMPLET/INCHOAT not needed
  • Atelic → no natural endpoint → coercion needed for endpoint reading

The telicity sensitivity split corresponds to the ordering direction: connectives with order ∈ {before, after} are telicity-sensitive; overlap/persistence connectives are not.

The Fragment's embeddedTelicityEffect for before is consistent with the data: before + stative is acceptable without coercion (default before-start reading), but before + accomplishment has a coerced alternative (before-finish via COMPLET).

The Fragment's embeddedTelicityEffect for after is consistent with the data: after + accomplishment is default (after-finish), but after + stative has a coerced alternative (after-start via INCHOAT).

The satisfiesDurativeRestriction predicate from the data layer is equivalent to the theory's isHomogeneous predicate on the canonical VendlerClass profile. This grounds the data-level predicate in the theory-level aspectual feature system.

INCHOAT extracts the onset of an atelic/stative denotation. The theory proves this equals the start point — connecting the Fragment's triggeredCoercion = "INCHOAT" to concrete behavior.

COMPLET extracts the telos of a telic denotation. The theory proves this equals the finish point — connecting the Fragment's triggeredCoercion = "COMPLET" to concrete behavior.

The Fragment entries that specify triggeredCoercion are exactly those that need aspectual adjustment for their complement type:

  • within_ triggers INCHOAT (needs onset of duration)
  • at_punct triggers COMPLET (needs telos of telic event)
  • before/after have triggeredCoercion = none because they have both default and coerced readings (specified via coercedReading).

When's coercion need correlates with the Vendler class: classes that are either stative or punctual need no coercion. This is because when selects a reference point, and statives trivially provide one (any subinterval) while achievements ARE a single point.

Instances For

    M&S's unified when-semantics agrees with the empirical coercion pattern: when needs no coercion iff whenCompatible is true. The M&S analysis explains the pattern: states are compatible because they're homogeneous; achievements because they already ARE culmination points. Processes and accomplishments require coercion because when must access a culmination they don't directly provide.
