Recent times  find the definition of the word "control" sliding in its own, newly wrong direction, throwing it and its users further off. "Control" is a slang word, now, for "mind control,"  slyly updated to correspond with our newly  updated forms of wage-slavery,  mind-enslavement, etc. Things endlessly condemned and dissected but never scheduled for redaction. Presumably as such redaction could peel back the surface to reveal who is "in"   in  in  "control"   control  control.  Sorry, did i just hear something? Anyways.

   The permission to graft this new hybrid of the meaning of the word "control" seems to be coming from a long-standing convention of smoothing together the "device-related" usage of it as a noun (entry 2, sense 3b, Webster's Collegiate 10th ed.) with the "slavery" variant of the "to exert a restraining or directing influence upon" usage as a verb (entry 1, sense 2a, ibid.) Now since the latter is an implied variation in usage, then I propose the term "implied variant" to describe such a thing.
