Zeugma \Zeug"ma\, n. [L., from Gr. ?, fr. ? to yoke, join. See
   {Yoke}.] (Gram.)
   A figure by which an adjective or verb, which agrees with a
   nearer word, is, by way of supplement, referred also to
   another more remote; as, ``hic illius arma, hic currus
   fuit;'' where fuit, which agrees directly with currus, is
   referred also to arma.
