Questions & Answers about Credo la tua supposizione sia giusta.
Why is the word che (that) missing after Credo?
In Italian, you can optionally drop the conjunction che (that) before a subordinate clause when its verb is in the subjunctive. This is especially common after verbs of thinking, hoping, or fearing, like credere. Both Credo che la tua supposizione sia giusta and the sentence shown here are completely correct.
Does dropping che change the tone of the sentence?
Just as a refresher, why must we use the subjunctive sia here instead of the indicative è?
Verbs like credere express personal opinion, belief, or uncertainty rather than objective fact. In Italian, expressing these subjective thoughts triggers the subjunctive mood in the clause that follows it, which is why we use sia.
If I used a verb of certainty instead of Credo, could I still drop the che?
No. Dropping che is a special feature of clauses that take the subjunctive (and occasionally the future tense). If you start with a verb of certainty like So (I know) which takes the indicative mood, you must keep the che. For example: So che la tua supposizione è giusta.
