Cisgender refers to a person whose gender identity matches the sex they were assigned at birth. In other words, a cisgender individual identifies with the same gender they were labeled as when they were born. For example, a person who was assigned female at birth and identifies as a woman is considered cisgender. Similarly, a person assigned male at birth who identifies as a man is also considered cisgender.
The term is often used to distinguish between individuals whose gender identity aligns with their assigned sex and those who are transgender, whose gender identity does not align with the sex they were assigned at birth.
Example:
A woman named Sarah, who was assigned female at birth and identifies as a woman, is considered cisgender. The term helps clarify distinctions between different gender identities, especially in discussions about gender diversity, and is used to ensure inclusivity when talking about the experiences of transgender people.
