Genderqueer: Genderqueer people typically reject notions of static categories of gender and embrace a fluidity of gender identity and often, though not always, sexual orientation. People who identify as "genderqueer" may see themselves as being both male and female, neither male nor female or as falling completely outside these categories.
Non-Binary (NB or enby): Anything that falls outside of the binary system (see definition above). Intersex, genderqueer, and bisexuality are all examples of non-binary identities.

"Some people have a gender which is neither male nor female and may identify as both male and female at one time, as different genders at different times, as no gender at all, or dispute the very idea of only two genders. The umbrella terms for such genders are 'genderqueer' or 'non-binary' genders. Such gender identities outside of the binary of female and male are increasingly being recognized in legal, medical and psychological systems and diagnostic classifications in line with the emerging presence and advocacy of these groups of people. Population-based studies show a small percentage – but a sizable proportion in terms of raw numbers – of people who identify as non-binary."

Gender Queer: a Memoir by 
Gabi, Between Ages 8 and 13
Nonbinary by
What happens when your gender doesn't fit neatly into the categories of male or female? Even mundane interactions like filling out a form or using a public bathroom can be a struggle when these designations prove inadequate. In this groundbreaking book, thirty authors highlight how our experiences are shaped by a deeply entrenched gender binary. The powerful first-person narratives of this collection show us a world where gender exists along a spectrum, a web, a multidimensional space. Nuanced storytellers break away from mainstream portrayals of gender diversity, cutting across lines of age, race, ethnicity, ability, class, religion, family, and relationships. From Suzi, who wonders whether she'll ever "feel" like a woman after living fifty years as a man, to Aubri, who grew up in a cash-strapped fundamentalist household, to Sand, who must reconcile the dual roles of trans advocate and therapist, the writers' conceptions of gender are inextricably intertwined with broader systemic issues. Labeled gender outlaws, gender rebels, genderqueer, or simply human, the voices in Nonbinary illustrate what life could be if we allowed the rigid categories of "man" and "woman" to loosen and bend. They speak to everyone who has questioned gender or has paused to wonder, What does it mean to be a man or a woman--and why do we care so much?

Gender identity, an issue that has galvanised the queer community in recent years, goes beyond the nature of male/female to a yet-to-be-traversed region that lies somewhere between and beyond biologically determined gender. In this groundbreaking anthology, three experts in gender studies and politics navigate around rigid, societally imposed concepts of two genders to discover and illuminate the limitless possibilities of identity.
