    Abstract: In the present research, we study the concept of
varietal nilpotent groups and prove some results about
their verbal and marginal subgroups. Also, we give some
relations between varietal nilpotent groups and cyclic
groups. Finally, we study the connection between
p-groups and varietal nilpotent groups.
