Clause Compression in Spanish

Spanish clause compression packages a finite proposition as an infinitive, participial or gerund clause, nominal group, or other reduced structure. Effective compression preserves who does what, when it happens, and how it relates logically to the main clause.

Clause Compression in Spanish: choices and models

DecisionGuidanceModel
Choose a form that preserves subject and timeAn infinitive is efficient when its understood subject is controlled by the matrix clause or explicitly introduced; a participle foregrounds a resulting state; a gerund normally presents a simultaneous process.

Spanish clause compression: Choose a form that preserves subject and time

An infinitive is efficient when its understood subject is controlled by the matrix clause or explicitly introduced; a participle foregrounds a resulting state; a gerund normally presents a simultaneous process. A finite clause is safer when subject or time must be stated independently.

Tras revisar el expediente, la comisión emitió su dictamen.
After reviewing the file, the committee issued its decision.The matrix subject la comisión naturally controls revisar, and tras establishes prior sequence.

Quick check

Which compression has a clearly controlled subject?

Preserve logical relations and participants

Compression can erase whether a clause expresses cause, purpose, concession, condition, or time. Keep a connector, preposition, or explicit participant when the relation is not uniquely recoverable.

Para que el equipo pudiera comparar los resultados, la dirección publicó los datos completos.
So that the team could compare the results, management published the complete data.The finite purpose clause preserves a subject different from la dirección.

Unpack competing compressed structures

Several nested nominalizations, infinitives, participles, or gerunds can create attachment and processing problems. Restore finite verbs where they reveal agency, sequence, or causal structure more efficiently.

Después de que el comité evaluó los datos, decidió revisar el protocolo antes de publicar los resultados.
After the committee evaluated the data, it decided to revise the protocol before publishing the results.The finite opening identifies the evaluator while the two controlled infinitives remain easy to recover.

Common mistakes

Tras revisar el expediente, se emitió el dictamen by an unidentified reviewer.

Tras revisar la comisión el expediente, se emitió el dictamen.

Giving the infinitive its own explicit subject prevents the impersonal main clause from hiding who reviewed the file.

Para comparar los resultados, la dirección publicó los datos when the team, not management, performs comparar.

Para permitir que el equipo comparara los resultados, la dirección publicó los datos.

The causative infinitive plus finite complement keeps both participants and the purpose relation visible.

Tras la evaluación de los datos para la revisión del protocolo antes de la publicación de los resultados por el comité...

El comité evaluó los datos, revisó el protocolo y después publicó los resultados.

Finite coordinated verbs expose the actions and their order more clearly than a chain of abstract nouns.

Clause compression FAQ

What does clause compression cover?

Spanish clause compression packages a finite proposition as an infinitive, participial or gerund clause, nominal group, or other reduced structure. Effective compression preserves who does what, when it happens, and how it relates logically to the main clause.

What is the first rule to remember?

An infinitive is efficient when its understood subject is controlled by the matrix clause or explicitly introduced; a participle foregrounds a resulting state; a gerund normally presents a simultaneous process. A finite clause is safer when subject or time must be stated independently.

What is another important C2 pattern?

Compression can erase whether a clause expresses cause, purpose, concession, condition, or time. Keep a connector, preposition, or explicit participant when the relation is not uniquely recoverable.
