late 14c., substitucion, "appointment of a subordinate or successor," from Old French substitucion, substitution or directly from Late Latin substitutionem (nominative substitutio) "a putting in place of (another)," noun of action from past-participle stem of Latin substituere "put in place of another, place under or next to, present, submit," from sub "under" (see sub-) + statuere "set up" (from PIE root *sta- "to stand, make or be firm," with derivatives meaning "place or thing that is standing").

In Latin assimilated to following -c-, -f-, -g-, -p-, and often -r- and -m-. In Old French the prefix appears in the full Latin form only "in learned adoptions of old Latin compounds" [OED], and in popular use it was represented by sous-, sou-; as in French souvenir from Latin subvenire, souscrire (Old French souzescrire) from subscribere, etc.
The original meaning is now obscured in many words from Latin (suggest, suspect, subject, etc.). The prefix is active in Modern English, sometimes meaning "subordinate" (as in subcontractor); "inferior" (17c., as in subhuman); "smaller" (18c.); "a part or division of" (c. 1800, as in subcontinent).
