On the basis of a effective "superconductivity"-type four-quark interaction, phenomenological Lagrangians are obtained for interactions of scalar, pseudoscalar, vector. and axial vector meson nonets. The Lagrangians include mass terms breaking chiral and U(3) invariance and corresponding to the quar
