Questions & Answers about ¿Cuándo se ve al monstruo?
Why does this sentence use se ve to mean 'does one see'?
Why is there an al before monstruo? I thought the personal a was only for people.
You are right that the personal a is mostly for people, but it is also used for pets, named animals, and personified beings. Since a monster is an animate, human-like creature, it gets the personal a. Here, the a combines with el to make the contraction al.
Can this sentence also translate to 'When is the monster seen?'
Yes, exactly! In Spanish, this impersonal se construction is used all the time where English would use the passive voice (like 'is seen' or 'are found'). Both translations work perfectly.
If there were multiple monsters, would the verb change to the plural ven?
