In the bosonization theory, we propose in this paper a definition of ``quasiparticles'' for interacting fermions at arbitrary space dimenions. In dimensions higher than one, we show that the constructed quasiparticles are consistent with quasiparticle descriptions in the Landau--Fermi-liquid theory, whereas in one dimension the quasiparticles are nonperturbative objects (spinons and holons) obeying fractional statistics. Application of our theory to Fermion liquids with singular Landau interaction is discussed.
