Questions & Answers about El detective se volvió obsesivo con el caso.
Why use se volvió for 'became' instead of se puso or se hizo?
Volverse is used to express a deep, often permanent or radical change in someone's personality, character, or behavior. Since becoming obsessive is a major psychological shift, se volvió is the natural choice. Se puso is for temporary physical or emotional states like se puso triste, and se hizo implies a voluntary change or effort like se hizo abogado.
Would se quedó also work in this sentence?
It would change the grammar and the nuance. Volverse obsesivo focuses on the ongoing transformation of his personality. Quedarse is used for the lasting result of an event, often a reaction or a physical state. If you used quedarse, you would normally pair it with a state rather than a trait, such as se quedó obsesionado, meaning 'he was left obsessed' rather than 'he became an obsessive person'.
Why does the Spanish sentence use con instead of a literal translation for 'about'?
In English, we often say someone is obsessive 'about' something. However, in Spanish, the adjective obsesivo as well as the related word obsesión almost always pair with the preposition con to introduce the target of the obsession.
Could I say se volvió obsesionado instead of obsesivo?
