Questions & Answers about Recuerdo nuestra cena en la casa de mi primo.
Why is recuerdo used here instead of me acuerdo?
Both recuerdo and me acuerdo come from the idea of remembering. Recuerdo is the first-person singular form of the verb recordar, and it literally translates to "I remember." Me acuerdo, on the other hand, comes from acordarse, which is a reflexive verb meaning roughly the same thing. In many contexts, they can be used interchangeably, but recordar (non-reflexive) sometimes has a slightly more direct feel. For example, Recuerdo nuestros viajes ("I remember our trips") sounds direct, while Me acuerdo de nuestros viajes expresses the same idea but in a slightly more reflexive manner.
What does nuestra refer to in nuestra cena?
The word nuestra is a possessive adjective meaning "our," referring to something that belongs to or is shared by the speaker and at least one other person. In this sentence, nuestra cena suggests that both you (the speaker) and someone else shared the dinner. It matches the feminine noun cena (dinner), hence nuestra rather than nuestro.
