Meaning
A circle combining three marks: the arrow of ♂️, the cross of ♀️ and a third stroke that merges both. It is the transgender symbol, representing trans people and gender diversity.
It appears in bios, pride posts, messages of support and inclusive forms or polls, often next to 🏳️⚧️: “Proud of you for being yourself ⚧️💙🤍💗” Many people use it to show they are allies. It is a respectful identity marker, not a symbol for jokes.
