Juxera is a gender that is strongly connected to femininity, but in a different way to how women are connected to femininity. Juxera is a something separate and entirely on its own. It may be described as a gender that is feminine aligned or fingender, but is not woman aligned or fiaspec, and has no connection to womanhood.
The term juxera was coined by Tumblr user Wulfgendur in July of 2014. The juxera and proxvir flags were created around the same time.
The pink and blue on the ends of the pentagon represent the “girl” and “boy” genders, while the blueish gray, navy, and purple represent the gender spectrum. The green triangle represent where the gender falls on the spectrum, which is “near girl” in the case of the juxera flag.
Jux- comes from the Latin adverb "juxta", meaning "near", and -era is a feminine noun for lady, mistress or goddess.
