Questions & Answers about En caso de que descubras una anomalía, debes saber cómo revertirla.
Why is descubras in the subjunctive here?
The phrase en caso de que always triggers the subjunctive because it introduces a contingency or hypothetical situation. By using descubras, you are preparing for the possibility of finding an anomaly, rather than stating it as a definite fact.
Could I just say en caso de descubrir without the que?
Yes. If you drop que, you must use the infinitive verb instead of the subjunctive. En caso de descubrir una anomalía means the exact same thing. This works perfectly here because the subject (you) is the same in both halves of the sentence.
Why is the pronoun la attached to the end of revertirla?
The pronoun la replaces the feminine noun anomalía. In Spanish, object pronouns can be attached directly to the end of an infinitive verb like revertir. Because the question word cómo starts a new phrase, attaching the pronoun to the infinitive is the only correct option here.
Why does cómo have an accent mark here if it isn't a direct question?
Words like cómo, qué, and dónde keep their written accent marks when they act as indirect questions. In this sentence, cómo revertirla is an embedded question explaining exactly what you need to know, so the accent is required.
