How time relationships are expressed in subordinate clauses in Spanish, English and Chinese.
Comparar idiomas
Temporal clauses express when an event happens relative to another. Spanish uses the indicative or subjunctive depending on certainty. English uses various conjunctions with normal tense. Chinese uses 的时候/之前/之后/当.
Overview
Temporal clauses indicate the time of an event relative to the main clause.
- Spanish: Uses indicative for factual/realized events, subjunctive for future, hypothetical, or non-factual events. Many temporal conjunctions require the subjunctive when the event is not yet realized.
- English: Uses normal tense sequences. Present tense is used in subordinate clauses even when the main clause is future. No mood distinction.
- Chinese: Uses postpositions (的时候, 之前, 之后, 以来) attached to the clause. 当 requires 的时候. The 一…就… construction expresses immediate sequence.
