Isogender

Isogender (Iso) is a gender modality that refers to when one is not cisgender, but also does not identify as transgender either. Examples of people who may identify as isogender include:

• A bigender, or otherwise multigender person doesn't feel trans because a significant portion of their gender is the same as their assigned gender at birth.
• A non-binary person who does not feel trans because their gender or gender presentation is similar to their assigned gender as birth. For example, a feminine aligned non-binary person who is AFAB.
• A genderless person who does not feel like trans describes them due to their lack of gender.

History

Isogender was coined by an anonymous ask to the Tumblr user Bigendering on June 9, 2018. The term "iso" comes from the word isomer, as cis and trans are isomer types.
