Learn Turkish: Yeni hastanenin temeli yarın atılacak. - The foundation of the new hospital will be laid tomorrow.

The verb root is at (from atmak). To make it passive, we add the passive suffix -ıl because the root ends in a consonant. Then, we add the future tense suffix -acak, giving us atılacak (will be laid).

Wait, doesn't atmak normally mean "to throw"? Why is it translated as "laid" here?

Yes, atmak usually means "to throw". However, Turkish uses the set phrase temel atmak to mean "to lay a foundation". So in the passive voice, temeli atılacak literally translates to "its foundation will be thrown," but naturally means "the foundation will be laid."

Can you break down the suffixes in the phrase hastanenin temeli?

This is a standard genitive-possessive pair linking two nouns to mean "the hospital's foundation". Hastane (hospital) gets the genitive suffix -nin (using an n buffer because it ends in a vowel) to mean "of the hospital". Temel (foundation) gets the third-person possessive suffix -i to show it belongs to the hospital.

Does temeli take an accusative (direct object) suffix here because the foundation is having an action done to it?

No, the -i on temeli is only the possessive suffix from the "hospital's foundation" relationship. In passive sentences, the "receiver" of the action becomes the grammatical subject. Since the foundation is the subject here, it does not take an accusative case marker.
