Names for United States citizens
Different languages use different terms for citizens of the United States, who are known in English as Americans. All forms of English refer to these people as "Americans", derived from "The United States of America", but there is some linguistic ambiguity over this due to the other senses of the word American, which can also refer to people from the Americas in general. Other languages, including French, Japanese, Chinese, and Russian, use cognates of "American" to refer to people from the United States, but others, like Spanish and Italian, primarily use terms derived from "United States". There are various other local and colloquial names for Americans.
Development of the term "American" 
First uses of the adjective "American" referenced European settlements in the New World. "Americans" referred to the indigenous peoples of the Americas, and subsequently to European settlers and their descendants. English use of the term "American" for people of European descent dates to the 17th century; the earliest recorded appearance is in Thomas Gage's The English-American: A New Survey of the West Indies in 1648. "American" especially applied to people in British America, and thus its use as a demonym for the United States derives by extension.
The United States Declaration of Independence of 1776 refers to "the thirteen united States of America", making the first formal use of the country name; the name was officially adopted by the nation's first governing constitution, the Articles of Confederation, in 1777. The Federalist Papers of 1787–1788, written by Alexander Hamilton, John Jay, and James Madison to advocate the ratification of the United States Constitution, use the word "American" in both its original, Pan-American sense, but also in its United States sense: Federalist Paper 24 refers to the "American possessions" of Britain and Spain, i.e. land outside of the United States, while Federalist Papers 51 and 70 refer to the United States as "the American republic". People from the United States increasingly referred to themselves as "Americans" through the end of the 18th century; the 1795 Treaty of Peace and Amity with the Barbary States refers to "American Citizens", and George Washington spoke to his people of "[t]he name of American, which belongs to you in your national capacity…" in his 1796 farewell address. Eventually, this usage spread through other English-speaking countries; the unqualified noun "American" in all forms of the English language now chiefly refers to natives or citizens of the United States; other senses are generally specified with a qualifier such as "Latin American" or "North American."
International use 
International speakers of English refer to people from the United States as "Americans", while equivalents of "American" are used in many other languages. French, German, Dutch, Italian, Japanese, Filipino, Chinese, Hebrew, Arabic, and Russian speakers use translations of American (Japanese: アメリカ人 rōmaji: amerika-jin), (Russian: американец, американка), (Mandarin Chinese: pinyin- měiguórén, traditional- 美國人, simplified- 美国人) to refer to U.S. citizens. Spanish and the Brazilian dialects of the Portuguese, use terms derived from Estados Unidos, the translation of "United States" – estadounidense and estadunidense, respectively. In European Portuguese the term americano is used to describe US citizens or things. Although the term estadunidense is growing in usage, in Brazil americano is still said to describe U.S. citizens. These languages, especially Portuguese in both its European and Brazilian variants, also use translations of North American: norteamericano and norte-americano. The same linguistic ambiguity that occurs in the English use of the term "American" occurs in the other European languages; to compensate for this, French (predominantly Quebec French) and Italian speakers may refer to U.S. citizens as États-unien and statunitense respectively, though this is less common. German speakers may distinguish between "American" and "US-American" (German: Amerikaner and US-Amerikaner, pronounced [uːɛsʔameʀiˈkaːnɐ]). This confusion is also present in Portuguese, as people from the United States may alternatively be referred to as americanos in that language. However, in Spanish, americano chiefly refers to all people from North and South America, and using it in the United States sense, may be considered offensive to Spanish speakers; the Diccionario Panhispánico de Dudas de la Real Academia Española recommends instead "estadounidense".
Alternative terms 
The only officially and commonly used alternative for referring to the people of the United States in English is to refer to them as citizens of that country. More generically, they may be specified as "U.S. Americans". Several single-word English alternatives for "American" have been suggested over time, including "Usonian", popularized by Frank Lloyd Wright, and the nonce term "United-Statesian". The writer H. L. Mencken collected a number of proposals from between 1789 and 1939, finding terms including "Columbian, Columbard, Fredonian, Frede, Unisian, United Statesian, Colonican, Appalacian, USian, Washingtonian, Usonian, Uessian, U-S-ian, Uesican, United Stater." Nevertheless no alternative to "American" is common in English. The only known language to have universally accepted Wright’s proposal is Esperanto, calling the country Usono and the citizens Usonanoj.
Spanish and Portuguese speakers may refer to people from the United States as norteamericanos and norte-americanos respectively ("North Americans"), though these terms can include Canadians and Mexicans. The Real Academia Española discourages the use of americano or americana for U.S. citizen, and recommends the use of estadounidense;  there are equivalent terms in Portuguese, French, and Italian. Other languages which optionally distinguish Pan-Americans from US-Americans include Japanese and Finnish; still others, such as Mandarin Chinese, Korean, Swahili, Vietnamese, and Esperanto, have two terms, neither with the ambiguity of English "American".
Colloquial terms 
"Yankee" (or "Yank") is a colloquial term for Americans in English; cognates can be found in other languages. Within the United States, "Yankee" usually refers to people specifically from New England or the Northern United States, though it has been applied to Americans generally since the 18th century, especially by the British. The earliest recorded use in this context is in a 1784 letter by Horatio Nelson. The word "gringo", often used derogatively, is common in Latin American Spanish and has entered into other languages including English, in which language it is recorded as early as 1871.
