Cisgender, or simply cis, is an adjective that describes a person whose gender identity aligns with the sex they were assigned at birth.

Gender binary is a system that constructs gender according to two discrete and opposite categories: boy/man and girl/woman. It is important to recognize that both cisgender and transgender people can have a gender identity that is binary. (

Gender-expansive is an umbrella term and adjective that can describe someone with a more flexible gender identity than might be associated with a typical gender binary. 

Gender expression is how a person presents gender outwardly, through behavior, clothing, voice, or other perceived characteristics. Society identifies these cues as masculine or feminine, although what is considered masculine or feminine changes over time and varies by culture.

Gender identity is one’s own internal sense of self and gender, whether that is man, woman, neither, or both. Unlike gender expression, gender identity is not outwardly visible to others.

For most people, gender identity aligns with the sex assigned at birth, the American Psychological Association notes. For transgender people, gender identity differs in varying degrees from the sex assigned at birth.

Nonbinary is a term that can be used by people who do not describe themselves or their genders as fitting into the categories of man or woman. A range of terms are used to refer to these experiences; nonbinary and genderqueer are among the terms that are sometimes used.

Transgender, or simply trans, is an adjective used to describe someone whose gender identity differs from the sex assigned at birth. A transgender man, for example, is someone who was listed as female at birth but whose gender identity is male.
