Questions & Answers about No hace falta que cierres la cremallera si solo vas a bajar un momento a la frutería.

What does no hace falta que mean, and how does this structure work?

No hace falta que + subjunctive is a very common way to say there’s no need for someone to... or you don’t need to...

In this sentence:

No hace falta que cierres la cremallera...

it means:

There’s no need for you to zip up / close the zip...

A useful pattern is:

Hace falta que + subjunctive = it’s necessary that...
No hace falta que + subjunctive = it isn’t necessary that...

It is an impersonal structure: Spanish does not say who makes the necessity happen; it just states whether something is necessary or not.

Why is cierres in the subjunctive?

Because no hace falta que triggers the subjunctive.

Spanish uses the subjunctive after many expressions of necessity, doubt, emotion, recommendation, etc. Here, the speaker is talking about whether an action is necessary, not simply stating a fact.

So:

No hace falta que cierres...
not
No hace falta que cierras...

The verb cierres is the present subjunctive of cerrar for tú.

Could I also say No hace falta cerrar la cremallera?
