1688, "student in the second year of university study," lit. "arguer," altered from sophumer (1653, from sophume, archaic variant form of sophism), probably by influence of folk etymology derivation from Gk. sophos "wise" + moros "foolish, dull." Short form soph is attested from 1778. Sophomoric "characteristic of a sophomore" (regarded as self-assured and opinionated but crude and immature) is attested from 1837.
popular tune of the Amer. Revolution, apparently written c.1755 by British Army surgeon Dr. Richard Schuckburgh while campaigning with Amherst's force in upper New York during the French and Indian War. The original verses mocked the colonial troops serving alongside the regulars, and the Doodle element just may have been, or hinted at, the 18c. slang term for "penis." The song naturally was popular with British troops in the colonies, but after the colonials began to win skirmishes with them in 1775, they took the tune as a patriotic prize and re-worked the lyrics. The current version seems to have been written in 1776 by Edward Bangs, a Harvard sophomore who also was a Minuteman.
