Questions & Answers about Bisogna che tu dia molta energia a questo personaggio.
Why is dia used here instead of the normal present tense dai?
The phrase bisogna che (it is necessary that) expresses a strong need or requirement. Impersonal expressions like this that end with che always trigger the subjunctive mood in the next part of the sentence, which is why we use the subjunctive form dia.
Dare is an -are verb, so shouldn't its subjunctive end in -i? Why is it dia?
Dare (to give) is a highly irregular verb. In the regular present subjunctive, -are verbs do end in -i, but for dare, the forms for io, tu, and lui/lei are all exactly the same: dia. Since it is an essential everyday verb, its irregular subjunctive forms just need to be memorized.
Could I say hai bisogno di dare instead of bisogna che tu dia?
Yes, you could say hai bisogno di dare molta energia, which literally means "you have need of giving". However, bisogna che (it is necessary that) is a very natural and common way to express a requirement in Italian. Remember that bisogna is impersonal, so it must be followed by che and a conjugated subjunctive verb when specifying who needs to do the action.
