What is a 'nickname'? Can you suggest another one for Private Quelch?
Army personnel, in their first week of training, together with the uniform, rifle and equipment, are ascribed a nick name. It is a name that defines their personality, representing their behaviour, nature and intellect.
Private Quelch was a man too interested to bask in the glory. He would talk in swaggering manner and display his knowledge without being asked. Proud in vain, he would go on pretentiously displaying how much he knew about all around. Once, on being asked if he had any training before, he replied, “No, Sergeant. It's all a matter of intelligent reading.” This defined his personality.
Hence, many nicknames can be suggested for “The Professor” defining his character such as braggart, trumpet, vaunter, etc.
