Etymology
Derived from the Latin "migratio," meaning the act of moving, which stems from the verb "migrare" (to move or change one's abode). The root is linked to "migrare," combining "mi-" (to move) with a suffix indicating action, evolving through Old French before entering English in the late 15th century to describe both biological and human movement.
