Learn Spanish (Latin America): Es importante que usted compruebe ese rumor. - It is important that you prove that rumor.

While you are currently learning about verbs of doubt like dudar que, impersonal expressions that show opinion, emotion, or urgency also trigger the subjunctive. Phrases like es importante que or es necesario que introduce a subjective idea or a desired outcome rather than a stated fact, so they require the subjunctive verb compruebe.

How do we get the form compruebe from the verb comprobar?

Comprobar (to prove or verify) is an 'o' to 'ue' stem-changing verb. To form the present subjunctive, you take the present tense 'yo' form (compruebo), drop the '-o', and add the opposite ending for '-ar' verbs, which for usted is '-e'. This results in compruebe.

Why is it ese rumor and not eso rumor?

When you are pointing out a specific masculine noun, you must use ese (that). Eso is the neuter form of 'that' and is only used for abstract ideas, statements, or unnamed objects. It is never used directly before a noun. Since rumor is a masculine singular noun, it has to be ese rumor.

Is comprobar a direct translation of 'to prove'?
