An island in the greater antilles in the west indies, south of florida. With the adjacent islands it forms the republic of cuba. Its capital is havana. It was discovered by columbus on his first voyage in 1492 and conquered by spain in 1511. It has a varied history under spain, great britain, and the united states but has been independent since 1902. The name cuba is said to be an indian name of unknown origin but the language that gave the name is extinct, so the etymology is a conjecture.
