Questions & Answers about Acepto, siempre y cuando no entres a mi cuarto sin tocar la puerta.
Why do we use the subjunctive entres instead of the indicative entras?
The phrase siempre y cuando (as long as / provided that) sets up a strict condition for the main action (acepto) to happen. Because this condition is a requirement for the situation rather than a declared fact, it always triggers the subjunctive.
Could I use con tal de que or siempre que instead of siempre y cuando here?
Yes, you could use either! Con tal de que, siempre que, and siempre y cuando are interchangeable when expressing a strict condition like "as long as" or "provided that". All three of these phrases require the subjunctive verb entres.
I learned that "to enter" is entrar en, but here it's entres a mi cuarto. Which preposition is right?
Both are correct, but it depends on the region. In Latin America, it is much more common to use the preposition a after entrar (entrar a mi cuarto). In Spain, you will typically hear entrar en.
Doesn't tocar la puerta literally mean "to touch the door"?
Since "you" are the one knocking, why is tocar left in the infinitive instead of being conjugated?
Because it directly follows the preposition sin (without). In Spanish, whenever a verb immediately follows a single preposition like sin, para, or por, it must remain in the infinitive (tocar). If the sentence used the phrase sin que, then you would need a conjugated subjunctive verb.
