Genderfluid is a gender identity which refers to a gender which varies over time. This can be occasionally, every month, every week, everyday, to even every few moments a day depending on the person. Sometimes it is consistent and sometimes it is not. A genderfluid person's gender may change dramatically, delicately, rapidly, or slowly also depending on the person. Somtimes a gender changes in response to different circumstances. Genderfluid is under the multigender umbrella. Genderfluid individuals can also identify as non-binary and/or transgender.
Genderfluid is also related to genderflux which shares a similar nature but act differently. (See genderflux for more information).
Genderfluid is also an umbrella term for genderfaunet, genderfaer, genderfloren, genderfrith, genderspirit, and genderfruct. Which most of these listed have their own subsets as well (and many of those subsets have their own subsets too).
Other subsets of genderfluid include: agenderfluid, fluidqueer, xenofluid, demifluid, lunagender, nuncgender, mutogender, magifluid, alysgender, cassfluid, quasifluid, cluttergender, parafluid, exofluid, condigender, demiofluid, occufluid, and noenfluid.
The first known mention of the word genderfluidity was in Kate Bornstein's book, Gender Outlaw: On Men, Women and the Rest of Us, in May 12th 1994. Genderfluid has been in use since at least the 1990s, however with a sometimes with different meanings. Trans advocate Michael M. Hernandez wrote in 1996 "Gender-fluid means that their gender identity and/or expression encompass both masculine and feminine. Gender fluidity is becoming commonly known as transgenderism: the ability to transcend gender, whether biological, emotional, political, or otherwise; truly mixing male and female." 
In the 1990s and 2000s, it was more common for a genderfluid individual to call themselves either bigender or genderqueer. The earliest dictionary entry for genderfluid was in 2007 on the Urban Dictionary. In 2010, the Gender-Fluid community was created on LiveJournal. On August 2nd 2012, lostinthoughtspaceandfantasies on Tumblr came up the offical and original genderfluid flag (that is known about). Lostinthoughtspaceandfantasies, also known as JJ Poole, would later go on to do an interview about it.
Annouced on May 6th 2015, Dictionary.com added an entry for genderfluid, which it defined as an adjective meaning "noting or relating to a person whose gender identity or gender expression is not fixed and shifts over time or depending on the situation."
