Thermal shape fluctuation models which are quite successful in the study of giant dipole resonance (GDR) in hot nuclei, have failed to explain the low temperature quenching of the GDR width. In the present work, we attempt to explain this behaviour in a relatively macroscopic approach. We take into account the fluctuations in the pairing field along with the thermal shape fluctuations to calculate the GDR width in hot nuclei. Our study reveals that the observed quenching of GDR width at low-T in the nuclei can be understood in terms of simple shape effects caused by the pairing correlations.
