\2290
The ⊐ symbol, officially named "Square Original Of" in Unicode, is a mathematical operator primarily used in advanced set theory and formal logic. It serves as a squared-off variation of the traditional "superset" symbol (⊃) and acts as the direct counterpart to the "Square Image Of" (⊏) operator. While rarely seen in casual texting, it frequently appears in complex technical documentation, LaTeX formulas, or as a structural piece in creative digital text art.
