Among its functions in Greek, apo- has the spatial sense “away, off, apart” (apogee; apocope; apostasy; apostrophe ); it occurs with deverbals that denote a response or defense (apodosis; apology ) and is found on verbs having perfective force relative to a corresponding simple verb (apoplexy; aposiopesis ). In modern scientific coinages in English and other languages, apo- marks things that are detached, separate, or derivative (apocarpous; apoenzyme ).
