initiate

This word carries a sense of formal authority and deliberate intent. It is far more structured than simply starting something; it implies the triggering of a sequence or the official launch of a protocol. In professional or legal settings, it suggests a precise point of origin from which a chain of events unfolds. When used in the context of social groups, it evokes a sense of transition and exclusivity. It describes the boundary between being an outsider and an insider, often involving a trial, a secret oath, or a specific set of rites that change the person's status within the hierarchy.
