\Hy*pal"la*ge\, n. [L., fr. Gr. ?, prop., interchange,
exchange, fr, ? to interchange; ? under + ? to change.]
(Gram.)
A figure consisting of a transference of attributes from
their proper subjects to other. Thus Virgil says, ``dare
classibus austros,'' to give the winds to the fleets, instead
of dare classibus austris, to give the fleets to the winds.

      The hypallage, of which Virgil is fonder than any other
      writer, is much the gravest fault in language.
