Hypallage

n. [ L., fr. Gr. &unr_;, prop., interchange, exchange, fr, &unr_; to interchange; &unr_; under + &unr_; to change. ] (Gram.) A figure consisting of a transference of attributes from their proper subjects to others. 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. [ 1913 Webster ]

The hypallage, of which Virgil is fonder than any other writer, is much the gravest fault in language. Landor. [ 1913 Webster ]
