We reanalyze the chiral Ward identities for the pseudoscalar mesons including the recently identified glueball state G(1440), in the hope that the solution for the decay constants will shed light on the interpretation of G(1440) as a gluonic bound state. Even when supplemented with experimental rates for (psi..-->..eta'..gamma..)/(psi..-->..eta..gamma..) and (eta'..--> gamma gamma..)/(eta..--> gamma gamma..)/(..pi../sup 0/+..gamma gamma..) we cannot obtain definite predictions for the pseudoscalar decay constants and for G..--> gamma gamma.., because the solutions are exceedingly sensitive to poorly known parameters. Classes of solutions are presented, which are functions of B(G..-->..KK-bar..pi..); a solution is only possible if B(G..-->..KK-bar..pi..)< or =30%. A typical value of GAMMA(G..--> gamma gamma..) is 5 keV, although much smaller values are quite reasonable.
