IntermediateConditional Mood
How languages express hypothetical, counterfactual, and uncertain situations in Spanish, English and Chinese.
Compare languages
The conditional mood expresses hypothetical or uncertain events. Spanish has a dedicated conditional verb form. English uses would/could/might + verb. Chinese uses 会/要是/如果 with aspect markers.
Overview
The conditional mood expresses hypothetical, uncertain, or counterfactual situations.
- Spanish: Has a dedicated conditional verb form (-ía endings). Used in hypothetical main clauses, reported speech, and polite requests. Combined with subjunctive in if-clauses.
- English: Uses modal auxiliaries: would (hypothetical result), could (ability/possibility), might (possibility), should (advice/obligation). No dedicated conditional verb form.
- Chinese: Uses 会 for hypothetical future, 要是/如果 for if-clauses, 能 for ability in hypothetical contexts. Aspect markers (了, 过) indicate relative time.
