Exception and Condition Clauses in Spanish

Advanced conditionals specify more than whether an event is possible. They can remove one exceptional case, state a sufficient requirement, issue a warning, or identify the enabling circumstance without which the result would be different.

Exception and Condition Clauses in Spanish: choices and models

Decision	Guidance	Model
Mark exceptions in Spanish exception and condition clauses	Use salvo que, a menos que, and excepto que plus subjunctive for an exception framed as a dependent possibility. Use excepto si when the exception is expressed as a full si condition.	Publicaremos el informe mañana, salvo que aparezcan nuevos datos.
State a sufficient condition precisely	Con tal de que and siempre y cuando introduce a condition considered sufficient for the result. They take the subjunctive because the speaker frames fulfillment as a requirement rather than an asserted fact.	Puedes modificar el diseño con tal de que mantengas la estructura principal.
Use marked warnings and counterfactual enabling circumstances	Como plus subjunctive can introduce a forceful warning whose consequence follows in the main clause. De no ser por plus noun identifies a circumstance that prevents a contrary result, often paired with the conditional.	Como vuelvas a divulgar los datos, cancelaremos el acuerdo. De no ser por tu intervención, ya lo habríamos cancelado.
