The word can be used as either an adjective or a noun (viz. a demonym). In adjectival use, it means "of or relating to the United States"; for example, "Elvis Presley was an American singer" or "the man prefers American English". In its noun form, the word generally means a resident or citizen of the US, but is also used for someone whose ethnic identity is simply "American" (Euro-American). The noun is rarely used in English to refer to people not connected to the United States when intending a geographical meaning. When used with a grammatical qualifier, the adjective "American" can mean "of or relating to the Americas", as in Latin American or Indigenous American. Less frequently, the adjective can take this meaning without a qualifier, as in "American Spanish dialects and pronunciation differ by country", or the name of the Organization of American States. A third use of the term pertains specifically to the indigenous peoples of the Americas, for instance, "In the 16th century, many Americans died from imported diseases during the European conquest", though this usage is rare, as "indigenous", "First Nations" or "Amerindian" are considered less confusing and generally more appropriate.
