Etymology
Origin of system
First recorded in 1610–20; from Late Latin systēma, from Greek sýstēma whole compounded of several parts, equivalent to sy- “”with, together” + stē- (variant stem of histánai “to cause to stand”; akin to Latin stāre “to stand” ) + -ma noun suffix denoting result of action; see sy-, stand
Explanation
A system is a group of things that connect and form some kind of coherent whole. All the individual buses and the separate routes they take through your city are together called a bus system. Any time various separate things act together in some organized way, you can call the entire group of interconnected things a system. Your veins, arteries, and heart together make up your body's circulatory system, and the group of planets which rotate around the sun are called a solar system. The Greek word systema, or "organized whole," is where system originates.
