a. United by hyphens; hyphened; as, a hyphenated or hyphened word. [ 1913 Webster ]

. An American who is referred to by a hyphenated term with the first word indicating an origin in a foreign country, and the second term being “American”, as Irish-American, Italian-American, African-American, Asian-American. Used in reference to Americans of foreign birth or ancestry. When used of Americans of European ancestry, it is often used to refer to those who have a strong attachment to the ancestral country or its culture. It implies that the individual is imperfectly assimilated into American culture, and is sometimes used derogatively. [ Webster 1913 Suppl. ]
