A retronym is a term consisting of a noun and a modifier which specifies the original meaning of the noun. For example, organic food is a retronym: a long time ago, all food was what we now consider “organic.” Retronyms can be objects (pedal bike), experiences (snow skiing), or even places (meatspace). Most of us use retronyms all the time without thinking about it.
