Breaking

undefined:

Breaking refers to the formation of a new headmate by breaking apart an existing member. This may result in one or several new members and/or fragments, with the original member remaining or disappearing. Since the original member "loses part of themself", this is also referred to destructive or reductive splitting.

Breaking may result in separate members, subsystems, syslings, or other types of connected or interlaced headmates.
