Questions & Answers about Sin embargo, la zona industrial se transformó en una pesadilla.
Why do we need the pronoun se in se transformó en?
Why use the preposition en instead of a literal translation for the English word into?
In Spanish, verbs of radical change that take a noun, like transformarse and convertirse, always lock in with the preposition en. While English uses into, Spanish relies on en to introduce the new state or identity.
Could I use se convirtió en in this sentence instead?
Why is transformó in the preterite tense here rather than the imperfect?
The preterite frames the change as a completed, definitive event. The zone became a nightmare, and that transition is finished. If you used the imperfect (se transformaba), it would mean it was in the process of turning into a nightmare over time, focusing on the ongoing background process rather than the final outcome.
