For the record, when bits are nicked off the front end of words it’s called aphesis, when off the back it’s called apocope, and when from the middle it’s syncope. A somewhat extreme example of the process is the naval shortening of forecastle to fo’c’sle, but the tendency to compress is as old as language itself. Daisy was once day’s eye, good-bye was God-be-with-you, hello was (possibly) whole-be-thou, shepherd was sheep herd, lord was loafward, every was everich, fortnight (a word curiously neglected in America) was fourteen-night.
