The word "expansion" originates from Latin expansionem (a spreading out), derived from expandere (to spread out). The morpheme ex- means "out," pans comes from pandere (to spread), and -ion is a noun-forming suffix indicating an action or process. The term evolved through Old French expansion before entering English, retaining its core meaning of "spreading outward."
