> What is a woman?

> A woman is an adult female human. Women are typically characterized by their reproductive biology, which includes their menstrual cycle, and the production of eggs and estrogen. Women are also known for their unique physical characteristics, such as their breast tissue and hips. They are also often distinguished by their social and cultural roles, such as their expected behavior and appearance. In general, the term "woman" is used to refer to any adult female person, regardless of her age, race, ethnicity, or other characteristics.
