The Formation of Inadvertent

It may look innocent, but inadvertent belongs to a class of words that provoke anger in many people who care about language – to wit, the back-formation. Bucking the usual trend in which longer words are formed from shorter ones by the addition of an affix (for example, superficiality from superficial), back-formations are created by clipping off a piece of a longer word; in this case, inadvertent was back-formed from inadvertence or inadvertency. A fair number of these words populate English, including brainwash (from brainwashing), complicit (from complicity), escalate (from escalator), and televise (from television). Certain back-formations, such as liaise (which comes from liaison) rub some people the wrong way. While they are under no obligation to accept liaise, there is nothing inherently wrong with back-formations; they are just another way our language has of creating new words.
