Deminonbinary is a gender in which one is partially, but not fully non-binary. They may or may not identify as another gender in addition to being partially non-binary. A deminonbinary individual may also consider themselves transgender.
Another definition of deminonbinary might be someone who feels non-binary, but still has a connection to somewhere in the binary.
Deminonbinary may also be used by individuals who feel little to no connection to femininity or masculinity, but usually do not experience a significant enough dissociation to create real physical discomfort or dysphoria.
The masculine equivalent to deminonbinary is demiboy, the feminine equivalent is demigirl, and the neutral equivalent is demineutrois. There are also demiagenders which are individuals who feel partly agender and partly another gender (usually a non masc, fem or neutral gender, example: partly aporagender).
History and flag
While the origin of the deminonbinary label is unknown, the label and yellow-stripe flag can be seen as early as June 21st, 2013. The meaning of the colors for that flag are mentioned to be as follows: grey for the partial nature of the gender, yellow for its non-binary nature, and white to represent all genders or its connection to being agender. That site attributes the yellow-stripe flag to Tumblr user alexander--the-great, whose account is no longer accessible. The purple-stripe alternative flag was posted by DeviantArt user Pride-Flags on July 4th, 2015, with the purple being a mixture of pink and blue representing masculinity and femininity.
