Questions & Answers about No digo que la difamación sea una mentira descabellada.
Why is the verb sea in the subjunctive here instead of the indicative es?
Because the main clause uses a negated verb of communication: no digo que (I do not say that). When verbs of declaring, stating, or communicating like decir, afirmar, or mencionar are negated, they deny a fact or introduce doubt. This triggers the subjunctive (sea) in the dependent clause.
Would I still use the subjunctive if the sentence were affirmative, like 'I say that...'?
No, you would use the indicative. If you say Digo que la difamación es una mentira, you are actively declaring something you consider to be a fact. It is specifically the negation (no digo) that shifts the tone from a declaration of truth to a denial, which requires the subjunctive.
How does the word descabellada translate to 'absurd'?
Can decir que trigger the subjunctive even when it is not negated?
