Origin: 1250–1300; Middle English < Latin: smaller, less; akin to Old English min small, Old Norse minni smaller, Gothic minniza younger, Sanskrit mīnāti (he) diminishes, destroys
1212, from L. minor "lesser, smaller, junior," formed as a masc./fem. of minus on the mistaken assumption that minus was a neut. comparative (see minus), from PIE base *min- "small" (cf. L. minuere, Gk. minythein, O.E. minsian "to diminish," Skt. miyate "diminishes, declines,"
Rus. men'she "less"). Some Eng. usages are via O.Fr. menor, from L. minor. Meaning "under-age" (adj.) is from 1579; the noun meaning "under-aged person" is from 1612. The musical sense is from 1694. In U.S. colleges and universities, "subject of study with fewer credits than a major," it is attested from 1890. In the baseball sense, minor league is from 1884; the figurative extension is first recorded 1926.
