We analyze the quark mass dependence of the chiral condensate and chiral susceptibilities in QCD with two degenerate light quark masses and a strange quark mass close to its physical value. We provide evidence for the influence of thermal fluctuations of Goldstone modes on the chiral condensate at finite temperature. We show that at temperatures below but close to the chiral phase transition at vanishing quark mass this leads to a characteristic dependence of the light quark chiral condensate on the square root of the light quark mass (ml). As a consequence the chiral susceptibility shows a strong quark mass dependence for all temperatures below Tc and diverges like 1/ √ ml the in chiral limit. We separately examine the divergence of disconnected and connected parts of the light quark susceptibility and discuss the cut-off dependence of susceptibilities and chiral condensates.
