'transmigration' originates from Latin, specifically the word 'transmigratio,' where 'trans-' meant 'across' and 'migrare' meant 'to move.'

'transmigratio' transformed into the French word 'transmigration,' and eventually became the modern English word 'transmigration' through Middle English.

Initially, it meant 'to move across or beyond,' but over time it evolved into its current meaning of 'the soul's passage after death into another body.'
