Implications of broken flavor-SU(3) symmetry are studied for J/psi and eta/sub c/ decays to two- and three-meson final states. Nonet-symmetry breaking and pseudoscalar-meson mixing are discussed using recent measurements of J/psi..-->..vector+pseudoscalar branching ratios by the Mark III collaboration. Detailed fits are presented to determine phenomenological parameters which describe the various mesonic decays of the J/psi. We conclude that the eta and eta' can be mixed with iota(1440), and predict B(J/psi..-->..iota..omega..) = (0.75 +- 0.12) x 10 -3 and B(J/psi..-->..iotaphi) = (0.09 +- 0.02) x 10 -3. In J/psi ..-->..pseudoscalar+pseudoscalar decays, electromagnetic and mass-breaking effects are found to be of similar importance. Different SU(3)-breaking patterns are observed in J/psi..-->..PV and eta/sub c/..-->..VV decays.
