Formation

undefined:

Formation refers to any process that results in the creation of a new headmate or system. This may include notable changes to existing members such as elaboration of fragments, only include elaboration that is connected to new members, or only refer to the formation up until a certain point after which elaboration may take place.

Different ways this can occur are listed under Category:Headmate Formation.

Splitting is the formation of a new headmate under stress, usually with the new headmate splitting off an existing member.

Pluralizing is the formation of a new headmate without splitting off an existing member.

Some may consider walk-ins and headmates that come out of dormancy to be formed, since they are joining the active system, while others may not use the term to refer to a process that a headmate has existed prior to.
