ex-member
No longer enrolled
An ex-member is a former member of a group, organization, or institution: ex-members of the band, ex-members of Congress.
The prefix signals departure—whether voluntary, involuntary, or through expulsion.
The term often carries weight when the former membership remains significant: an ex-member of a cult, ex-members speaking out against the organization.
