Questions & Answers about Bu makine düzenli olarak yağlanmalı.

In Bu makine düzenli olarak yağlanmalı, what kind of verb form is yağlanmalı?

Yağlanmalı is a third-person singular verb in the passive voice combined with the -malı suffix, which expresses necessity/obligation. Literally, “it must be oiled.”

What does the suffix -malı indicate here?

The suffix -malı/-meli is used to show that something must happen or should happen. It adds a sense of deontic necessity (obligation) to the verb.

Why is the verb in the passive voice (yağlanmalı) rather than active?

Using the passive focuses on the action itself (“being oiled”) rather than who is doing it. Often in instructions or maintenance manuals, the agent (person who oils) is unimportant or implied, so you use the passive.

Why is there no direct object in the sentence?

In Turkish, when you turn an active verb into passive, the original object either becomes the subject or is dropped. Here, bu makine is the subject (nominative) and there is no separate direct object.
