We have proposed earlier a paired cluster (PC) model for high Tc superconductivity mechanism. We show here that this model is able to explain the pseudogap origin and other gap related properties of cuprates. As per PC model, singlet coupled magnetic cluster pairs are present in the cuprates, in the material's otherwise paramagnetic state below a temperature TCF, where an ionic spin of cluster 1 forms a singlet pair with a corresponding ionic spin of cluster 2. The conducting electrons (CEs) for T>=Tc and both the CEs and the Cooper pairs (CPs) for T=T>=Tc, with d-wave symmetry which superimposes over the BCS superconducting state (SS) energy gap for T
