a word invented (usually unwittingly by subtracting an affix) on the assumption that a familiar word derives from it, such as emote from emotion.
the process of inventing a back-formation{1}.
Word formation based on a mistaken morphological analysis. Usually this means dropping a part of the word when it is incorrectly thought to be an affix. In the case of "duh" and "Doh!" it has been done with a change in the vowel and other phonological refinements.
a coined verb which was formed from an already existing noun, and the result is technically not a dictionary term
a word invented in the erroneous belief that an existing word is derived from it
A new word produced by analogy when people remove a supposed affix from the perceived stem of a word; the verb peddle was created in English when people began removing the supposed affix -ar from the noun peddlar.
In etymology, the process of back-formation is the creation of a neologism by reinterpreting an earlier word as a derivation and removing apparent affixes, or more generally, by reconstructing an "original" form from any kind of derived form (including abbreviations or inflected forms). The resulting new word is called a back-formation.
