Questions & Answers about Acabamos reventando la bolsa por el susto.
Why is it acabamos reventando instead of using a preposition like acabamos de reventar?
When you want to say you "ended up doing" something, you use the verb acabar (or terminar) followed directly by a gerund (an -ando or -iendo word). So, acabamos reventando means "we ended up bursting". If you said acabamos de reventar, that uses the "acabar de + infinitive" structure, which means "we just finished bursting" or "we have just burst".
Does acabamos here mean "we end up" (present) or "we ended up" (past)?
In this translation it means "we ended up" (past tense), but it could actually be either! For verbs ending in -ar, the nosotros (we) form is spelled exactly the same in both the present tense and the simple past (preterite) tense. You have to rely on context to know when it happened.
Could I use terminamos instead of acabamos in this sentence?
I remember reventar having a stem change. Why isn't it revientando?
