The article studies an unusual type of shortening known in English linguistics as telescope words. It is well known that Lewis Carroll was the first to introduce this new type of shortening and defined it using the term telescope words. It was one of his purposes to create a pun. Later this type of word formation proved to be highly productive in the English language. Some linguists suggest that this phenomenon is based on an incidental slip of the tongue and blending of one or two sounds of the full prototype’s clipped components in free speech.
