dc.description.abstract	The notion of spin squeezing involves a reduction in the uncertainty of a component of the spin vector vecS below a certain limit. This aspect has been studied earlier (Mallesh et al 2000a <A article="0305-4470/33/4/310">J. Phys. A: Math. Gen. 33 779</A>, Mallesh et al 2000b <A article="0305-4470/34/15/308">J. Phys. A: Math. Gen. 34 3293</A>) for pure and mixed states of definite spin. In this paper, this study has been extended to coupled spin states which do not possess a sharp spin value. A general squeezing criterion has been obtained such that a direct product state for two spinors is not squeezed. The squeezing aspect of entangled states is studied in relation to their spin-spin correlations	en
