Learn Turkish: Yönetim, sistem çok hantal olduğu için otomasyonu zorunlu kıldı. - The management rendered automation mandatory because the system was very cumbersome.

While yaptı means 'made' or 'did', kılmak is a formal auxiliary verb meaning 'to render' or 'to make into a certain state'. It pairs with adjectives (like zorunlu) to show an official change in status. You will often see it in legal, administrative, or academic contexts.

Why is otomasyon in the accusative case (otomasyonu) while zorunlu is not?

The verb kılmak requires a definite direct object for the thing being transformed. Here, the management is taking specific action upon 'the automation', making it the direct object (otomasyonu). Zorunlu (mandatory) is the adjective describing the new state, so it takes no case endings.

Does olduğu için mean 'because it was' in the past tense?

The structure -dIği için covers both past and present reasons. We know it translates to 'because it was' rather than 'because it is' solely because the main verb of the sentence (kıldı) is in the past tense. The -dIk participle itself just means the action is not in the future.

Can hantal be used for things other than abstract systems?

Yes, hantal literally means bulky, clumsy, or physically heavy. It can describe a heavy piece of furniture or an uncoordinated person, but at the B2 level, it is very common to see it used metaphorically for a slow, inefficient bureaucracy or process.
