("America") and is "country". The name for the American continents is , from plus ("continent"). Thus, a is an American in the continent sense, and a is an American in the U.S. sense. Conversely, in Czech, there is no possibility for disambiguation. Američan (m.) and američanka (f.) can refer to persons from the United States or from the continents of the Americas, and there is no specific word capable of distinguishing the two meanings.
