Appendix:English back-formations

An English back-formation refers to either the process of creating a new lexeme (less precisely, a new "word") by removing actual or supposed affixes, or to the neologism formed by such a process. Back-formations are shortened words created from longer words. Back-formations are different from clipping in that they often change the word class (part of speech) of the word.

Each back-formation in this list is followed by the original word from which it was back-formed.
