Migrate, emigrate, and immigrate are all about being on the move. The source of all three is the Latin word migrare, which means “to move from one place to another.” Emigrate and immigrate sound alike, and both involve leaving one location and arriving in another, but they are applied differently: emigrate stresses leaving the original place, while immigrate focuses on arriving in the new one. You won’t have trouble keeping them straight if you remember that the prefix e- means “away,” as in eject, and the prefix im- or in- means “into,” as in inject.
