Learn Turkish: Yazar, basına röportaj vermemiş. - The writer apparently didn't give an interview to the press.

It combines the verb root ver- (to give), the negative suffix -me, and the inferential past tense suffix -miş. The inferential past tense shows that the speaker didn't witness this firsthand; they either heard it from someone else or figured it out. This is why we add words like "apparently" or "reportedly" in the English translation.

Why is there an "-a" at the end of "basına"?

The base word is basın (the press). The -a is the dative case suffix, which translates to "to" or "towards". Just like in English, you give an interview "to" someone, so the verb vermek requires the receiver (basın) to take this "to" suffix.

Why doesn't "röportaj" have a specific direct object suffix like "-ı"?

Because it is an indefinite direct object in this sentence. The sentence means the writer didn't give "an" interview, rather than "the" specific interview. In Turkish, when a direct object is general or indefinite like this, it doesn't take the accusative case suffix and must sit directly next to the verb.

Why is there a comma after "Yazar"?

The comma is used to clearly mark Yazar (the writer) as the subject of the sentence. In Turkish, separating the subject with a comma when it is far from the verb or followed by other nouns makes the sentence much easier to parse and prevents any confusion about who is doing the action.
