What Does “AFAB” Mean? (Definition & Origin)

AFAB stands for:
👉 Assigned Female At Birth

It refers to a person who was labeled female when they were born based on physical anatomy (like external genitalia).

Key Points:

• It describes biological assignment at birth, not necessarily current identity.
• A person who is AFAB may or may not identify as a woman.
• It’s commonly used in conversations about gender identity, inclusivity, and LGBTQ+ topics.

Origin of AFAB

The term originated in medical and academic contexts, where doctors assign a sex (male or female) at birth. Over time, it became widely used in online communities, especially in discussions about gender diversity.

Why Not Just Say “Female”?

Because AFAB ≠ gender identity.

For example:

• Someone can be AFAB but identify as non-binary or male.
• The term avoids assumptions and is considered more inclusive and precise.
