Questions & Answers about Quem te envia o anexo?
Why does te come before the verb here instead of after it?
In European Portuguese, pronouns normally attach to the end of the verb. However, question words like Quem (Who) act as magnets. They pull the object pronoun to the front of the verb, so we must say Quem te envia instead of Quem envia-te.
Since te refers to the informal you, why isn't the verb conjugated as envias?
Is te acting as a direct or indirect object pronoun in this sentence?
It is an indirect object pronoun. The verb enviar (to send) takes a direct object for the thing being sent (o anexo) and an indirect object for the person receiving it (te, meaning to you).
