Abstract
This talk contains an analysis of quenched chiral perturbation theory and its consequences. The chiral behavior of a number of quantities such as the pion mass m{sub {pi}}{sup 2}, the Bernard-Golterman ratios R and {chi}, the masses of nucleons, and the kaon B-parameter are examined to see if the singular terms induced by the additional Goldstone boson, {eta}`, are visible in present data. The overall conclusion of this analysis is that even though there are some caveats attached to the indications of the extra terms induced by {eta}` loops, the standard expressions break down when extrapolating the quenched data with m{sub q}
