Learn Turkish: Doktor rahatsızlık için yeni bir tedavi bulacak. - The doctor will find a new treatment for the disorder.

It is built from three parts: rahat (comfortable or at ease), plus the negative suffix -sız (without) to make rahatsız (uncomfortable or unwell), plus the noun-building suffix -lık to make rahatsızlık (discomfort, illness, or disorder).

Why is the word order yeni bir tedavi and not bir yeni tedavi?

In English, we say 'a new treatment', putting the article first. In Turkish, when you use a descriptive adjective alongside bir (a/an), the adjective almost always comes first. The literal word order is 'new a treatment'.

Why doesn't tedavi (treatment) have an accusative case ending if it is the direct object?

Because it is an indefinite object. The doctor is looking for 'a' new treatment, not a specific, already-known treatment. If they were looking for 'the' new treatment, it would need the accusative ending and become tedaviyi.

How is the future tense formed in bulacak?

It takes the verb root bul- (to find) and adds the future tense suffix -acak. We use -acak rather than -ecek because of A-type vowel harmony with the back vowel 'u' in bul-. There is no extra personal suffix at the end because the subject is third-person singular (the doctor).
