Learn Italian: Mi pare che il cuoco dica la verità. - It seems to me that the cook is telling the truth.

The phrase mi pare che (it seems to me that) expresses a personal opinion or impression. In Italian, verbs of opinion, belief, and doubt followed by che require the verb in the next part of the sentence to be in the subjunctive mood. So, the indicative dice becomes the subjunctive dica.

How does mi pare work? Is it related to sembrare?

Yes! Parere (to seem or to appear) is very similar to sembrare. In the phrase mi pare, the mi is an indirect object pronoun meaning "to me." You can use mi pare che and mi sembra che completely interchangeably to express an opinion and trigger the subjunctive.

Dire is an -ire verb, so why does its subjunctive form end in -a (dica)?

Dire is an irregular verb. Its present subjunctive is built from its irregular root, giving us the base dic-. In the present subjunctive, all three singular forms (I, you, he/she/it) share the exact same ending: dica. Here, it simply matches the third-person subject il cuoco (the cook).

If I am 100% sure the cook is telling the truth, can I use the indicative dice instead?
