  It is pointed out that heavy top quark mass can be attributed to a singular
normalization of its kinetic term, in which rescaling into canonical one yields
large top Yukawa coupling. We pursue this novel possibility in a democratic
mass matrix model where only the normalization of the third generation can be
different from that of the other two generations. With diagonal breaking of
democratic S_3 symmetry, we show that the singular normalization for the top
quark is essential to reproduce observed quark masses and mixing angles. We
also briefly argue other applications of this mechanism.
