Learn Farsi: مرد عصبانی خودش را کنترل نمی‌کند.

It is built using the base word خود (self) plus the third-person singular ending ـش (his/her), making خودش. Because 'himself' is the direct object receiving the action of the verb, we must follow it with the specific direct object marker را, giving us خودش را.

Could we drop the را after خودش?

No. The word را is required for specific direct objects. Reflexive pronouns like خودش point to a very specific person (in this case, the angry man), so they always need را when they are the object of the sentence.

How does the negative verb کنترل نمی‌کند work here?

This is a compound verb made of the noun کنترل (control) and the verb کردن (to do). To make the present tense negative, we only change the verb part. We add the negative prefix نـ (ne-) right before the continuous prefix می (mi-), resulting in نمی‌کند (nemi-konad).

How are the words for 'angry' and 'man' linked?

They are linked by the ezafe, which is a short 'e' sound added to the end of the first word. In Farsi, the noun comes first, so we say مردِ عصبانی (mard-e 'asabâni), which literally flows like 'man [e] angry'.
