the word "transmigration" is a compound formed from latin elements. the prefix "trans-" signifies movement across a boundary, while the root "migr-" carries the core meaning of moving or changing abode. combined with the noun-forming suffix "-ation," the term literally denotes the process of moving across. its earliest english usage in the 14th century referred to the physical migration of people. the more specialized philosophical and religious sense, concerning the journey of a soul across bodies after death, developed later, drawing on the metaphorical extension of crossing from one state of being into another. this semantic evolution illustrates how a concrete concept of spatial movement was abstracted to describe a metaphysical passage.
