Questions & Answers about Voy a cuidar a mi abuela hasta que se haga anciana.
Why do we use se haga here to mean 'becomes'?
The verb hacerse is used for changes that happen gradually over time, like aging or changing your political beliefs. Since getting old is a natural, progressive process, we use hacerse with the adjective anciana (elderly).
Why is hacerse in the subjunctive form (haga)?
We use the subjunctive after hasta que (until) when we are talking about an event in the future that has not happened yet. Since the grandmother is not elderly yet, we need the subjunctive haga instead of the present indicative hace.
Why is there an a between cuidar and mi abuela?
This is the personal a. In Spanish, when the direct object of a verb (the thing or person receiving the action) is a specific person, you must put the preposition a right before it. Here, the grandmother is the specific person receiving the care.
