What role does täytyy play in the sentence, and how does it function?

Täytyy is a modal verb that expresses necessity or obligation—similar to the English “must” or “have to.” In this sentence, it indicates that the listener is required to remember to close the door. It sets up the idea that the action is not optional but mandatory.

Why is the infinitive form sulkea used after muistaa?

In Finnish, when one verb follows another to describe an intended action, the second verb is typically in the infinitive form. Here, muistaa (“to remember”) is followed by sulkea (“to close”), which specifies what should be remembered. This construction is similar to the English “remember to close the door,” where the action remains in the infinitive.

How does the subordinate clause kun lähdet function in the sentence?
