Double Union Symbol Meaning
⋓ (DOUBLE UNION, U+22D3) is a mathematical symbol in the Unicode set. As its name suggests, it represents a “double” union concept—an operation or relationship that combines elements in a union-like way. In practice, you’ll mostly see it in math writing, where a standard union symbol alone isn’t sufficient to convey the intended structure. Because it’s a dedicated Unicode math character, it’s best used when you specifically need this exact glyph rather than a plain “U” or a generic union character. When sharing or publishing, copy it via Unicode to avoid font or encoding mismatches.
Common uses
- •Use in math notes to represent a double union operation or relationship
- •Include in academic or technical documents that use Unicode math symbols
- •Label set-combination steps in diagrams or worksheets
- •Write consistent symbols in LaTeX-like documentation (via Unicode copy/paste)
- •Create UI text for math tools or equation editors that support U+22D3
