Back- formation is. considered to be the opposite process of suffixation. As we know, suffixation is thenformation of new words by adding suffixes to bases，and back-formation, is therefore the. method of creating words by removing the supposed suffixes. This is because many of the removed suffixes are not true suffixes but inseparable parts of the words. For example，the verb edit is made by dropping the. ending-or in editor.
Clipping is another way of making a word.It is. to*shorten a longer word by cutting apart off the original and using what remains instead. Back clipping keeps the front part of the word, dropping the remaining syllables, ,such as dorm for dormitory.
