Questions & Answers about Non sono convinto che il rompicapo sia così ambiguo.
Why is the subjunctive sia used here instead of the indicative è?
Would I still use the subjunctive if the sentence were positive (Sono convinto che...)?
Usually, no! Saying Sono convinto che (I am convinced that) expresses strong certainty, which triggers the regular indicative mood. You would typically say Sono convinto che il rompicapo è così ambiguo. It is specifically the negative word Non in this sentence that creates the doubt requiring the subjunctive.
Does the word convinto change depending on who is speaking?
Rompicapo is an interesting word for puzzle. How is it formed?
It is a compound noun made from the verb rompere (to break) and the noun capo (head). So, a rompicapo is literally a head-breaker, which is a highly descriptive way to refer to a difficult puzzle or brain-teaser!
