After a proper definition of the dimerization order parameter for a spin-S system, I show that this order parameter in the SU(n) (n=2S+1) antiferromagnetic chains (or equivalently the SU(2) spin-S chains with Hamiltonians which project out singlet states) is, in the thermodynamic limit, directly proportional to the staggered-magnetization in the corresponding spin-1\over2 XXZ chains which had already been mapped onto the SU(n) chains.
