Back-formation
In
etymology, back-formation refers to the process of creating a new
lexeme (less precisely, a new "word") by removing actual or supposed
affixes. The resulting
neologism is called a back-formation. Back-formations are shortened words created from longer words, thus back-formations may be viewed as a sub-type of
clipping.
