in the statement 'luego fernando y yo fuimos a la tienda de equipo deportivo para mirar patines' is the preterite in the ser sense or in the ir sense. Explain how we know this.
In the statement "luego fernando y yo fuimos a la tienda de equipo deportivo para mirar patines" (later, Fernando and I went to the sports equipment store to look at skates), the verb "fuimos" is in the preterite tense.
We know this because "fuimos" is the preterite tense form of the verb "ser" in the 1st person plural (nosotros). In this context, "fuimos" does not refer to the verb "ir" (to go), but rather to "ser" (to be). The preterite form of "ir" in the 1st person plural would be "íbamos." So, the use of "fuimos" indicates that "ser" is being used in the preterite tense, implying that it is describing a past action.
