Questions & Answers about Confido la tua supposizione sia valida.
Where is the word che (that) in this sentence?
In Italian, you can optionally drop the conjunction che before a subordinate clause, but generally only if the verb in that clause is in the subjunctive mood. Because confidare triggers the subjunctive (sia), you can say Confido la tua supposizione sia valida instead of Confido che la tua supposizione sia valida. This omission makes the sentence sound slightly more elegant and is very common in higher-level written or spoken Italian.
Why do we use the subjunctive sia instead of the indicative è here?
The verb confidare expresses a personal expectation, hope, or belief rather than a stated objective fact. Just like other verbs of hoping, believing, or fearing (such as sperare or credere), it requires the subjunctive mood in the following clause.
If I changed the main verb to so (I know), could I still drop che?
How does confidare differ from sperare (to hope) or fidarsi (to trust)?
Confidare in this context means 'to trust' or 'to feel confident' that something is true. It bridges the gap between sperare (which is a simple hope) and fidarsi (which is used for trusting a person or entity, e.g., Mi fido di te). You use confidare when you are banking on a specific situation or outcome being true.
