- sub: From Latin sub-, meaning "under" or "instead of." Here, it implies replacement.
- stit: From Latin statuere (to set, stand), related to status (position). The root conveys the idea of "placing" or "standing in."
- ution: A noun-forming suffix derived from Latin -tio, indicating an action or process.
Etymology Origin:
The word traces back to Latin substitutio, combining sub- (replacement) + statuere (to place). It originally described the act of "placing under" or "appointing a successor." Over time, it broadened to mean any replacement, retaining its logical structure: sub- (instead) + stit (position) + -ution (action).
