Webster's Dictionary (GCIDE)

Adios \A`dios"\ ([aum]`dy[-o]s"), interj. [Sp., fr. L. ad to + deus god. Cf. Adieu.] Adieu; farewell; good-by; -- chiefly used among Spanish-speaking people; as, adios amigos (good-bye friends). [Webster 1913 Suppl.]

Note: This word is often pronounced [.a]*d[=e]"[-o]s, but the Spanish accent, though weak, is on the final syllable. [Webster 1913 Suppl.]
