Definition and Pronunciation
Fluid is an adjective used to describe something that is flexible, changeable, or not fixed. In discussions of sexuality and gender, it often refers to a person’s gender identity, gender expression, sexual orientation, or romantic orientation changing or varying over time rather than remaining constant.
Pronunciation: FLOO-id
Easy Explanation
In everyday English, fluid means able to change or flow easily. In the context of identity and sexuality, it means that a person’s feelings, identity, or attractions may change naturally over time instead of staying the same throughout life.
For example, someone who identifies as gender-fluid may experience their gender differently at different times. Similarly, a person may describe their sexual or romantic orientation as fluid if the people they are attracted to change over time.
Being fluid is a valid way some people describe their experiences, and it does not imply confusion, indecision, or uncertainty.
