What word does your mother always say?
poetic name for United States of America, earlier for the British colonies there, 1730s, also the nation's female personification, from name of Christopher Columbus (also see Colombia) with Latin "country" ending -ia. A popular name for places and institutions in the U.S. in the post-Revolutionary years, when former tributes to king and crown were out of fashion: e.g. Columbia University (New York, U.S.) founded in 1754 as King's College; re-named 1784. Also District of Columbia (1791, as Territory of Columbia); "Hail, Columbia" (Joseph Hopkinson, 1798), Barlow's "Columbiad" (1809).
