Learn Turkish: Misafirler yarın otelden ayrılacak. - The guests will leave the hotel tomorrow.

The verb root is ayrıl (to leave). Since it ends in a consonant, we attach the suffix directly without needing a buffer y. The last vowel in the root is ı, so we follow major vowel harmony and use the back-vowel version of the future suffix, which is -acak.

Why does the word for hotel (otel) have the -den (from) ending here?

In English, you 'leave a place,' using a direct object. But in Turkish, the verb ayrılmak (to leave/depart) requires the ablative case (-den or -dan). Turkish speakers literally say they are departing from a place.

The subject misafirler (guests) is plural. Why doesn't the verb have a plural ending like ayrılacaklar?

When a plural human subject is already explicitly stated in the sentence, adding the plural suffix -lar or -ler to the verb is optional. Misafirler yarın otelden ayrılacaklar is also perfectly correct, but dropping the ending on the verb is very common and avoids repetition.

Is the verb root ayrıl related to other words?

Yes! It translates to 'to leave' or 'to depart,' but it actually comes from the verb ayırmak (to separate). Ayrılmak is the reflexive form, essentially meaning 'to separate oneself' from a place.
