We by no means expect people to memorize this list. It's partly here for people who aren't fully aware of system things and also for our own benefit.

For the common terms, if we have a different definition we use for our system, we will put it first, and the "official" definition under it in super script.

This is not a comprehensive list. Feel free to ask us to include something if you feel we ought to.

Most (if not all) definitions are from this website mostly because it's the easiest to read, as well as Pluralpedia.

Common Terms

Amnesia: memory loss, can be for specific events or periods of times

Alter(s)/Headmate(s): a separate presence of an identity. All alters may adapt and change over time, and some may even choose to take on the form of fictional characters if that serves a helpful purpose.

a type of a protector, they help manage and care for other alters

Co-fronting/Co-concious: two or more alters each being aware of the other's presence, and having an on-going memory of a situation or particular period of time. One is normally in "executive control" of the person's body, while another is able to watch, listen and think about what is happening. The alters who are co-conscious with one another will not necessarily behave as one.
