Learn Turkish: Kuvvetler mühimmatı karargâha getirdi. - The forces brought the ammunition to the headquarters.

First, you add the causative suffix -t to get getirtmek (to make someone bring). Then, you add the passive suffix -il to get getirtilmek (to be caused to be brought). If the sentence was 'The ammunition was caused to be brought to the headquarters,' it would be: Mühimmat karargâha getirtildi.

Wait, does the verb getirmek (to bring) already have a causative suffix in it?

Yes, it does! Historically, getirmek is a smoothed-down version of gelmek (to come) plus the causative suffix -tir. So, literally, geltirmek meant 'to cause to come,' which perfectly describes the act of bringing something. Over time, it evolved into its own word, getirmek.

Why does mühimmat take the -ı suffix while karargâh takes the -a suffix?

They take different cases because of their different roles in the sentence. Mühimmatı (the ammunition) has the accusative -ı because it is the specific direct object receiving the action. Karargâha (to the headquarters) has the dative -a because it shows the destination of the bringing action.

What is the purpose of the circumflex (hat) on the 'â' in karargâha?
