Questions & Answers about Fue en la trituradora donde empezó a triturar los papeles.
What is the purpose of saying Fue en la trituradora donde... instead of just starting with Empezó a triturar...?
This is a cleft sentence (oración hendida) used for emphasis. By framing the location with Fue... donde... (It was... where...), the speaker highlights exactly where the action took place, putting a spotlight on the shredder rather than just stating a simple fact.
Do I have to include the preposition en after Fue? Could I just say Fue la trituradora donde...?
You must include en. In Spanish cleft sentences, the emphasized element keeps whatever preposition it would normally take. Since you shred papers en (in) a shredder, that preposition stays attached to la trituradora when it is moved to the front for emphasis.
Why is the verb ser conjugated in the preterite (fue) instead of the imperfect (era)?
In cleft sentences, the tense of ser usually matches the tense of the main action. Because the main verb empezó is in the preterite (a completed past action), ser also takes the preterite form fue.
Why is there an a between empezó and triturar?
