Cisn't (also known as Cisgendern't, Noncisgender or Cisdissident) is an umbrella term for anyone who is not cisgender. It is not exclusive to transgender people, as not all non-cis people identify as trans. Even though trans may apply to them, they may not identify primarily as trans, because they do not feel they experience the trans experience. Cisn't includes other gender modalities, such as ipsogender, ultergender, isogender, demicisgender, etc. as well as trans.
