A backronym is not a retronym. A backronym is something along the lines of Port Out Starboard Home for the origin of posh. A retronym is the addition of an adjective for the purpose of discriminating between types to a noun phrase that previous did not need one. Examples would be acoustic guitar or analog watch.
