¿Te importa si me uno a ti?

✦Grammar Breakdown
¿Teimportasimeunoati?
Indirect object pronoun (te)
‘Te’ is the second‑person singular indirect object pronoun, used here with the impersonal verb ‘importar’ to ask about the listener’s feelings.
Impersonal verb ‘importar’
‘Importar’ works like ‘to matter’; the subject is the thing that matters (the action of joining), and the person who cares is expressed with the indirect object pronoun.
Conditional clause ‘si…’
‘Si’ introduces a yes/no condition, equivalent to ‘if’ in English.
Reflexive pronoun ‘me’
‘Me’ is the first‑person singular reflexive pronoun that belongs to the verb ‘unirse’ (to join).
Verb ‘unirse’ (to join)
Conjugated in the present ‘uno’ (I join). It is a pronominal verb, so it always needs the reflexive pronoun.
Preposition ‘a’ + prepositional pronoun ‘ti’
When the object of ‘unirse’ is a person, the preposition ‘a’ is required, followed by the prepositional pronoun ‘ti’ (to you).

✕Common Mistakes
¿Te importa si me uno contigo?
‘Contigo’ is a fused form of ‘con + tú’; after ‘unirse a’ you must use the prepositional pronoun ‘ti’, not ‘contigo’.
¿Te importa si me uno a tú?
After a preposition you must use the prepositional pronoun ‘ti’, not the subject pronoun ‘tú’.
¿Te importa si me uno a ti
The question mark at the end of the sentence is required in Spanish punctuation.

Cultural Tip
In Spanish‑speaking cultures, asking for permission with ‘¿Te importa…?’ shows respect for personal space and group dynamics. It is slightly more formal than ‘¿Puedo…?’ and can soften a request that might otherwise feel intrusive. Remember that ‘ti’ is used after prepositions; using ‘tú’ here would be grammatically incorrect.
