The notions of pure ideals and pure submodules play an important role
in the study of rings and their module categories. In this paper, we i
ntroduce right t-pure fuzzy ideals and pure fuzzy submodules of an R-m
odule. We establish their basic properties, and use them to obtain fuz
zy theoretic characterizations of right weakly regular rings. Among ot
her results, we prove that a ring R is right weakly regular if and onl
y if each fuzzy submodule of a cyclic R-module is pure fuzzy.
