Interjection | The most neglected part of speech in Punjab, Pakistan

Let me take the opportunity to break this sad news that Interjection is the most neglected part of speech. Specifically, it's importance is overlooked in the school or colleges of Punjab, Pakistan particularly Rawalpindi.
To my utter surprise, a lecturer of local university has no understanding of this part of speech. She was also at that time preparing for her B.Ed.and totally taken aback with respect to Interjection and it's uses in English language.
So let me give in black and white A to Z of interjections commonly used in the language. However, it is needless to mention here, I am going to give the definition of this part of speech!
