Learn Spanish (Latin America): El jurado va a decidir el caso mañana. - The jury is going to decide the case tomorrow.

To form the affirmative usted command for regular -ir verbs like decidir, you swap the normal ending for an -a. So you would say, ¡Decida el caso!

A jury has multiple people. Why does it use the singular verb 'va' instead of the plural 'van'?

Even though a jury involves multiple people, the word el jurado is grammatically singular. Spanish treats collective nouns based on their grammar, not their meaning—if the noun is singular, the verb must be singular. Other common examples are la familia (the family) and la gente (the people).

Is it better to say 'va a decidir' (is going to decide) or use the future tense 'decidirá' (will decide)?

Both are grammatically correct, but va a decidir (ir a + infinitive) is much more common in everyday spoken Latin American Spanish. Native speakers strongly prefer this structure when talking about plans in the near future, like things happening mañana.

I've seen 'mañana' used to mean 'morning'. How do I know it means 'tomorrow' here?
