This paper developed the concept of normal sub-intuitionistic fuzzy Multigroups.It then established that intersection, union, of any two normal subintuitionistic fuzzy multigroups is also normal.The inverse of any normal subintuitionistic fuzzy multigroup is normal and for any normal sub-intuitionistic fuzzy multigroup, the root (support) set of normal sub-intuitionistic fuzzy multigroup is a normal sub-intuitionistic fuzzy group.It also showed that under the isomorphism function between any two groups, the image of a normal sub-intuitionistic fuzzy multigroup under the isomorphism is a normal sub-intuitionistic fuzzy multigroup and the inverse image of a normal sub-intuitionistic fuzzy multigroup under the isomorphism is a normal subintuitionistic fuzzy multigroup.
