e/Verbal subgroup

Information
has gloss	eng: In mathematics, especially in the area of abstract algebra known as group theory, a verbal subgroup is a special sort of subgroup of a group that can be defined as all elements that can be expressed as products of a special form, called a word. Verbal subgroups are particularly important as the only characteristic subgroups of a free group and therefore represent the generic example of characteristic subgroups.
