  The purpose of this paper is to show that the symmetry breaking into special
subgroups is not special at all, contrary to the usual wisdom. To demonstrate
this explicitly, we examine dynamical symmetry breaking pattern in 4D $SU(N)$
Nambu--Jona-Lasinio type models in which the fermion matter belongs to an
irreducible representation of $SU(N)$. The potential analysis shows that for
almost all cases at the potential minimum the $SU(N)$ group symmetry is broken
to its special subgroups such as $SO(N)$ or $USp(N)$ when symmetry breaking
occurs.
