In Yes/No questions the answer is either yes or no. For instance, “Did you see Tom?” is a Yes/No question in English.
To make a Yes/No question in English we need an auxiliary verb (e.g. do, did, have, etc.) which normally comes in the beginning of the sentence.
Did you see Tom?
In Persian we do not need to change the structure of the statement in order to make a question. All we need to do is put the word “āyā” in the beginning of the sentence.
