Meaning
A circle with a small cross underneath, the traditional sign for female, also known as the symbol of Venus. It is used in biology and medicine and, more broadly, for women and girls.
People use it in profiles, polls, team lists and posts about women’s rights or Women’s Day: “Girls’ team ♀️ meets at 8” Behind the scenes it is also the piece that turns many activity emoji into their woman version, like 🏃♀️. Its counterpart is ♂️.
