Genderfluid or simply fluid, refers to someone whose gender identity changes over time. A genderfluid individual can identify as any gender, or combination of genders, at any given time. Their gender can change at random, or it may vary in response to different circumstances. At times, these individuals may identify as male, female, both, or neither. Their pronouns may vary at different times. The term genderfluid can be used as a specific identity in itself or as a descriptive term. They are generally considered under the non-binary and transgender umbrellas, but not all genderfluid individuals identify with those terms. Some genderfluid people transition socially, physically, and/or legally.
