Questions & Answers about Una debe usar un candado en la taquilla.
Why does this sentence use Una instead of Uno for 'one'?
I learned taquilla as 'box office' or 'ticket window'. Why is it translated as 'locker' here?
In Spain, taquilla is the standard word for both a ticket window and a personal locker (like you would use at a gym, school, or train station). You have to rely on context, and using a padlock (un candado) points clearly to a locker.
Why don't we need a linking word like que between debe and usar?
The verb deber (must/should) connects directly to an infinitive verb like usar without any preposition or linking word. This is different from the phrase tener que, which also expresses obligation but requires que (as in Una tiene que usar).
The English translation says 'on the locker', so why does the Spanish sentence use en?
The Spanish preposition en is very flexible and commonly translates to 'in', 'on', or 'at' depending on the situation. When talking about attaching a padlock to a locker, en is the most natural choice.
