Riddle: What English word retains the same pronunciation, even after you take away four of its five letters?
Answer: From the question, it is clear that the answer is a word with five letters. Also one of the letters of the alphabet has the same pronunciation.
So starting from the first letter, a… and continuing with b… c… d we go till q, which is the letter with the same pronunciation as word queue. The queue is the required word.
