Learn Hardcore Turkish: Hastane kalabalık.

In Turkish, the present simple copula (the verb to be) is commonly omitted. The sentence directly states the condition of the hospital without an extra word for is, making Hastane kalabalık a natural and complete expression.

What does kalabalık mean in this context, and can it act as both an adjective and a noun?

Kalabalık means crowded when used as an adjective—as it does here to describe the hospital. Although the same word can also be a noun meaning crowd, its position following the subject hastane shows it functions as a predicate adjective.

Why is there no article like the before hastane in this sentence?

Turkish does not use definite or indefinite articles such as the or a. The noun hastane simply means hospital, and context tells us whether it is specific or general.

Could the sentence include a copula suffix, and what would that look like?

Yes, for a more formal or written style you can add a third-person singular copula suffix. For example, Hastane kalabalıktır uses -dır (adjusted to -dir or -dur based on vowel harmony) to explicitly state is, though in everyday speech this suffix is usually omitted.

What is the word order in Hastane kalabalık, and how does it compare to English?

The word order here is a subject followed by a predicate adjective. In English we say "The hospital is crowded", where crowded describes the subject. Turkish likewise places kalabalık after hastane but drops the linking verb, yet the structure still conveys the state of the subject.

How would you turn Hastane kalabalık into a question asking "Is the hospital crowded?"

To form a yes/no question in Turkish, you add the interrogative particle mı to the end. Thus, Hastane kalabalık mı? directly translates to "Is the hospital crowded?" in English.
