Questions & Answers about Usen el portal por si el monstruo se regenera y se vuelve inmune.
Since this lesson is about the prefix re- as an intensifier, does regenera mean 'generates a lot'?
Good catch, but no! While you've been learning the colloquial prefix re- meaning "very" (like rebién meaning "very good"), here re- works just like it does in English: it means "again". When attached to verbs like generar (to generate), it almost always means repetition (to generate again), not intensity.
Why is se regenera in the present indicative? Doesn't 'in case' imply doubt, which usually triggers the subjunctive?
That's a very common mix-up! Despite expressing a hypothetical situation, the phrase por si (in case) is followed by the present indicative when the possibility is seen as realistic or likely. You would only use the subjunctive (specifically the past subjunctive) if the event was highly unlikely: por si el monstruo se regenerara (just in case the monster were to regenerate).
Why do we use se vuelve for 'becomes' here instead of another verb like se pone or llega a ser?
Spanish has several verbs for "to become." Volverse is used for involuntary, often profound or lasting changes in a condition or state (like becoming immune or going crazy). Ponerse is used for temporary physical or emotional states (like getting sad or turning red), and llegar a ser implies a gradual process requiring effort (like becoming a doctor).
