Undefined (Age)

Undefined is an age term for system members whose ages are undefinable or vague. While people whose ages are undefined could use ageless, it's a more specific term for someone who isn't really "older than dirt, so they don't have a quantifiable age", but more "age literally can't be applied".
In basic terms, someone who not only doesn't have an age, but not an age range either, due to the nature of age being too confusing or non-applicable.
Some examples;
* Androids, or other types of people who were created (so they're technically "a few days old", but are also adult coded, etc)
* Non-humans, whose ages differ from humans, so their age can't really be defined in a human way.
* Age sliders, who aren't really sure when they slide, either, so their age is always flickering to different ages.
* Any person who doesn't have an age, but does have a "coded" age. Someone who doesn't have a number, but acts like a teenager, as an example.
== History ==
While the definition has been floating around, Capri Suns & Gushers 🍒🐙 "coined" undefined, mostly in Discord spaces, PluralKit, and some random posts/asks/etc.
That being said, it's a pretty easy to accidentally "coin" term, and many have used similar language for the same thing. CS&G doesn't consider it a coinable term.

Unstable Personality

An unstable personality is when a headmate's personality “breaks” or “shatters” and then suddenly becomes a completely different one which is more distorted and/or unstable each time. It can also be at the same level of unstableness or distortion each time it shatters and becomes different. Their personality may do this due to stressful events/trauma/etc. but not always. 
This happens to their personality, not their whole person. This can also be due to a disorder.

Untamed One

A untamed one is a role that's very broad, but mainly revolves around being non-human or a shapeshifter. This is achieved by managing and holding symptoms and traits of being non-human, helping other headmates deal with nonhuman instincts or impulses in a positive and healthy way, by being a specialized masker for nonhuman traits, and to generally just be more comfortable and functional as a non-human headmate. Some of the functions of this role are as follows, please note this is not an extensive list of tasks performed by this role.
# Absorb, redistribute, or neutralize distressing emotions or thoughts around or about being non-human or a shapeshifter.
# Controlling, redistributing, neutralizing, or absorbing nonhuman impulses, instincts, or traits of other headmate.
# Neutralize or Soothe pain and other symptoms (both an innerworld and in the outerworld) caused by changing forms.
# Absorbing, redistributing, controlling, neutralizing, or soothe dysphoria that might be experienced by another nonhuman or shapeshifter.
# Encouraging a healthy balance and relationship with nonhuman instincts, impulses, and traits instead of suppressing them. This may be achieved through by play, both in the innerworld and the outerworld.
# Calming, soothing, and comforting other headmates about non-human traits, impulses, and instincts.
# Managing feelings of humanity (in reference to the state of being human) amongst specific headmates, layers, groups, subgroups, sidesystems, subsystems, or the system as a whole.
# Holding nonhuman symptoms, traits, instincts, impulses for as specified as a specific headmate or as general as the whole system.
# Masking nonhuman traits or tendencies if a headmate is unable to mask them sufficiently or in a healthy way.
# Encouraging healthy play (especially animalistic or non-human play) amongst and with other headmates, outerworld pets or animals, and outerworld people.
# Embracing and accepting a non-human life experience. Embracing instead of suppressing nonhuman traits and tendencies, this may be in themselves, others, or the system as a whole.
This headmate is usually nonhuman themselves, but this is not required. This role is also not intended to be specific to any animal, supernatural being, or creature.
==History==
Originally coined by Overbythefishtank on July 3, 2023 to describe Ciaran and his functions in their system as there was not a term that fully encompasses Ciaran's role. This role was coined to be traumagenic-exclusive due to the circumstances around Ciaran and why they split.

Urgenic

Urgenic is an origin term for a headmate or system that may have formed from, or to hold onto urges, impulses, or habits. https://urgenic.carrd.co/
Systems or headmates may consider themselves to be urgenic if:
* Urges, impulses, habits, needs, or similar are very powerful to ones identity, how they identify, and/or how they represent to others and themselves.
* They keep an urge, impulse or habit contained, one which often controls their way of acting, thinking, speaking or approaching a situation or people.
* These urges (or related impulses) effect their daily life and cause hardship in handling their daily routine.
== Name ==
The term "urgenic" is derived from the word "urge" and "genic", merging the common "ge" letters. Thus, it is a simplified version of "urge genic".
== Flag Meaning ==
The blush red/pink strips on the outside represent showing or expressing one's urges, whether privately or openly for comfort. The carmine red inner stripes represent recognizing one's habits and impulses, whether they are good or bad. The central wine red stripe shows solidarity in aiming for stability in one's impulses, or already knowing how to control them. https://urgenic.carrd.co/#flags
There are three variants of this flag beyond the basic meaning:
* One with black spikes covering the entirety of the flag. It represents someone still in the process of learning to overcome bad habits.
* One with black spikes covering two-thirds of the flag. It represents someone further along in the process of learning to overcome their bad habits or impulses, and that progress is being made.
* One with no black spikes over the flag. It represents someone who doesn't know the strength of their habits, do not wish to reveal such information, or have mostly overcome those problems.

Urgetaker

An urgetaker is a headmate who carefully minds the actions and desires of impeters, urge holders, and other system members who may cause bodily harm. Urgetakers protect the system by either ensuring these members engage with dangerous or harmful behaviors as safely as possible, or by enacting the desired behavior themself in a safe and controlled manner.
An urgetaker may, for example, ensure first aid kits are available for the system, ensure dangerous or reckless activities are done with safety equipment, or carefully control the degree to which their system can act on dangerous impulses or harmful urges. They may also be the sole member of a system allowed to act on certain urges or impulses, as they are trusted to do so safety.
Urgetakers may also act as (or work closely with) gatekeepers while dangerous activities are performed, keeping more sensitive or reactive individuals out of front until danger passes. They may also take control of front themselves to ensure an impulse is not acted on, or is acted on as carefully as possible.
Urgetakers can be considered a type of protector, as their role focuses heavily on harm-reduction and ensuring the safety of their system. They may also be impeters or urge holders themselves.

Vacantspace

A vacantspace (or vacantvoidspace) is a headspace that is empty. It could appear to be a place, but no headmates appear, or it could just be a void.
Headmates not appearing could be because they don't have access to the layer/sisasystem, are in another area, or the system can't visualise their headmates well (this could be due to aphantasia, lack of practice, etc.)
==Related Terms==
A variaspace is a sentient headspace that was empty at first (much like a vacantspace), but then decided to constantly change its locations and appearance as soon as a system formed in it.
A blankspace is a sentient headspace whose purpose is to be artistic, acting as a canvas. When it is inactive, the headspace appears to be completely empty and could be mistaken as a vacantspace. It can become a vacantspace if the sentient entity fades or become dormant; until a trace of activity appears again.
The synonym vacantvoidspace was coined to help distinguish a vacantspace that is only void from one that is not only void, even though the terms may be used interchangeably.
