The origin of Yankee has been the subject of much debate. The first recorded use of the term by the British to refer to Americans in general appears in the 1780s, in a letter by Lord Horatio Nelson, no less. Around the same time it began to be abbreviated to Yank. During the American Revolution, American soldiers adopted this term of derision as a term of national pride. The derisive use nonetheless remained alive and even intensified in the South during the Civil War, when it referred not to all Americans but to those loyal to the Union. Now the term carries less emotion—except of course for baseball fans.

Historically, the term usually refers to residents of New England, as used by Mark Twain in "A Connecticut Yankee in King Arthur's Court". Outside the USA, Yank or Yankee is one of the lesser derogatory slang terms for any American, whether from New England or not.
Johnathan Hastings of Cambridge, Massachusetts was attributed around 1713 to regularly using the word as a superlative, generally in the sense of excellent.
