Questions & Answers about نمیدانید که آیا خروجی متغیر دارد یا خیر.
Why does the sentence end with yâ kheyr instead of the more common yâ na?
yâ kheyr means exactly the same thing as yâ na (or not), but it is highly formal. It fits perfectly here because words like khoruji (output) and moteghayer (variable) suggest a technical, academic, or professional context, such as computer science or math, where formal language is expected.
Do I always have to use both ke and âyâ together to mean 'whether'?
In formal written Farsi, you will frequently see them paired as ke âyâ to introduce a reported yes/no question. However, the ke is technically optional. In less formal Farsi, you might see just âyâ, and in everyday speech, speakers often drop both and rely entirely on tone.
Could I place the verb dârad at the very end of the sentence, after yâ kheyr?
No, you should keep the alternative ending yâ kheyr (or yâ na) at the very end of the sentence. The standard structure for these reported questions is to finish the core clause first (khoruji moteghayer dârad) and then append the alternative polarity at the tail.
Is the word moteghayer related to the concept of change?
Yes! It comes from an Arabic root meaning to change or alter. In everyday Farsi, it can mean changing or fluctuating, like the weather. In technical contexts like this sentence, it is the standard noun for a mathematical or programming variable.
