The therian symbol is a Greek Theta Θ and Delta Δ interlocked. The symbol is used by the therian community, which is made up of people who identify as therians. A therian identifies as a particular non-human being, usually some kind of animal, like a dog, bird, or fox.

The symbol most commonly used to represent therianthropy is called the “theta delta”, because it is the greek symbols theta and delta overlapping. Delta is used in science to represent changes in variables, although I have no idea why what connection the theta symbol has to therianthropy.

Theta-Delta is the most widely used symbol in representing Therianthropy. The symbol consists of two Greek letters layered on top of each other: the Delta and the Theta characters. Both characters are typically depicted in the same color against a contrasting single color background, and may be styled further by intertwining the letters.

A key emblem representing this identity is the Theta-Delta symbol (ΘΔ). This article delves into the origins, meaning, and significance of the therian symbol, providing a comprehensive understanding of its role within the community.

These are pride flags for any alterhuman, not just only therians. And totally free to use, I wish to see someone using them! And I'll also show you two flags I was talking about earlier, the first did by @/Kei The Therian on Amino and the second by @/SCP2547 "coyote" on Twitter
