- second (adj.)
- "after first," c.1300, from O.Fr. second, from L. secundus "following, next in order," from root of sequi "follow" (see sequel). Replaced native other (q.v.) in this sense because of the ambiguousness of the earlier word. Second-hand is from 1474; second-rate is from 1669, originally of ships (see rate); second sight is from 1616; an etymologically perverse term, since it means in reality the sight of events before, not after, they occur. Second fiddle first attested 1809.
