Word Origin & History

meta- 
prefix meaning 1. "after, behind," 2. "changed, altered," 3. "higher, beyond," from Gk. meta (prep.) "in the midst of, among, with, after," from PIE *me- "in the middle" (cf. Goth. miþ, O.E. mið "with, together with, among," see mid). Notion of "changing places with" probably led to senses "change of place, order, or nature," which was the principal meaning of the Gk. word when used as a prefix. Third sense, "higher, beyond," is due to misinterpretation of metaphysics (q.v.) as "transcending physical science."
