Questions & Answers about Mañana también voy a felicitar a mi hermano por sus buenas notas.

Why is there an a before mi hermano?

In Spanish, this is the personal a, which is used before a direct object that is a person (or a pet you treat like a person). It doesn’t translate directly into English, but it’s a grammatical requirement in Spanish to show that mi hermano is the direct object of voy a felicitar.

Why do we say mañana también voy a felicitar instead of mañana voy también a felicitar?

In Spanish, the adverb (también) can either be placed before the main verb or at other positions for emphasis, but it usually flows naturally after mañana and before voy. Placing también in a different spot isn’t wrong in every case, but it often sounds more natural where it is.

Could we say felicitaré instead of voy a felicitar?

Yes, it’s grammatically correct to use the future tense (felicitaré). However, using voy a felicitar can sound more immediate and colloquial, essentially emphasizing the intent to do it. Both forms are valid; they just convey slightly different tones.

Why is the preposition por used before sus buenas notas?

In Spanish, por often indicates the reason or cause of an action. Here, it tells us the reason for congratulating your brother: he got good grades. Other Spanish prepositions like para or de wouldn’t correctly convey the same idea of “because of” or “due to.”

Does sus refer to the speaker’s brother or someone else’s?

Sus is a possessive adjective that agrees with the noun it modifies (buenas notas). In this sentence, sus is referring back to the brother. In context, it means his good grades. If the subject had been a different person, you would clarify it from context or by using a name to avoid confusion.
