Learn Farsi: آنها پرسیدند که آیا ابراز خشم لازم است؟ - They asked if the expression of anger is necessary?

ابراز follows the Arabic Form IV (Ef'âl) pattern, which indicates causation or realization. The root consonants are b-r-z (ب-ر-ز), which mean 'protruding' or 'becoming manifest'. By plugging those roots into the e-C1-C2-â-C3 pattern, we get e-b-r-â-z, meaning 'to make something manifest' or 'expression'.

Why do we have both که and آیا right next to each other?

In English, indirect questions are introduced with 'if' or 'whether'. Farsi, however, often introduces indirect speech with the conjunction که (that), followed immediately by the question exactly as it was asked. Literally, this sentence reads: 'They asked that: is the expression of anger necessary?'

Can I use آیا for 'if' in conditional sentences too?

No, آیا is strictly a question marker used for yes/no questions (acting somewhat like 'whether' here). You can only use it in this sentence because the subjects are literally asking a question. If you want to say 'if' for a condition, such as 'If you are angry...', you must use اگر (agar).

Is there an Ezafe between ابراز and خشم?

Yes, it is pronounced ebrâz-e khashm. Even though ابراز is an Arabic verbal noun, it behaves like any regular Farsi noun in a sentence. The hidden Ezafe links the action noun ('expression') to its target ('anger'), translating naturally to 'the expression of anger'.
