Partly borrowed from Middle French sisteme, systeme, partly directly from its etymon Late Latin systēma (“harmony; musical scale; set of celestial objects; set of troops; system”), from Ancient Greek σύστημα (sústēma, “musical scale; organized body; whole made of several parts または members”), from σῠνίστημῐ (sunístēmi, “to combine, organize”) + -μᾰ (-ma, resultative suffix). σῠνίστημῐ is from σῠν- (sun-, “with, together”) + ἵστημι (hístēmi, “to stand”), from Proto-Indo-European *steh₂- (“to stand (up)”).^[1]

Cognate with Dutch systeem, modern French système, German System, Italian sistema, Portuguese sistema, Spanish sistema.
