Nonpuerella or Nonvirmina refers to someone who is both nonpuella and nonpuer. They are not male, partially male, or male-aligned in any way and they are not female, partially female, or female-aligned in any way. However they still experience some connection to both masculinity and femininity in their gender. It can also be described as a gender that is lingender or androgynous but is not liaspec, miaspec/male-aligned, or fiaspec/female-aligned. Nonpuerella can be used as a gender on it own, or it can be used to encompass several genders, such as censari.
It is unknown who coined nonpuerella or its main flag. The alternate flag was designed by tumblr user nbandproud on September 29, 2016.
The meanings of the colors of the alternate flag are-
The purple is for femininity and masculinity;
The green is for the separation of this gender from the gender binary;
The star is for simultaneous separation and connection- stars are separate from Earth but still seen from it and seen as together with it, like how nonpuer people are separate from malehood but still in connection with masculinity.
Puer is the latin word meaning "boy", while puella is the latin word meaning "girl".
