What is the term for admitting someone as a member of a group or organization?

The term "induct" refers specifically to the formal process of admitting someone into a group or organization. This process often includes a ceremony or an official procedure that signifies the individual's acceptance and membership within the group. Induction is commonly associated with organizations like clubs, societies, or any formal associations where there are specific criteria or rituals for membership.

While "integrate," "incorporate," and "enroll" can imply various forms of inclusion or joining, they do not carry the same formal connotation as "induct." Integrating can refer to merging or blending into a larger group, whereas incorporating typically refers to forming a legal entity or organization. Enrolling usually applies to signing up or registering for courses, classes, or programs rather than indicating formal membership in a group context. Thus, "induct" is the most precise term for the formal admission process.
