Emigrate comes from Latin emigratus, past participle of emigrare ('to move away, depart from a place'), from e- ('out') + migrare ('to move, travel'). Morphologically, the form is compositional: e- marks part of the visible structure, while the remaining element supplies the lexical base. In present use, it is used as a verb meaning "to leave one's own country to settle permanently in another", so the historical material remains connected with the current sense rather than standing as bare ancestry. The wider English family includes derivatives such as emigration and emigrant and related forms such as migrate, immigrate, and migration, showing how the same historical material continues to organize neighboring vocabulary. The named historical forms include Latin emigrare and Latin migrare, keeping the history tied to concrete forms rather than a loose resemblance. Its semantic neighborhood is marked by migrate, relocate, resettle, and depart on one side and contrasts such as immigrate, remain, and stay on the other, locating the modern specialization without adding a new origin story.
