U+231D\urcorner⌝⌝<mo>⌝</mo>Semantic identity and intent
Characters to distinguish
- + — Plus Sign
- − — Minus Sign
- × — Multiplication Sign
Use ⌝ in the right format
Meaning and usage
Marks the upper right corner used to group expressions, denote inner products, intervals, semantics, or specialized mathematical structures.
Always pair ⌝ with its matching delimiter and choose scalable LaTeX delimiters for tall fractions, matrices, and nested expressions.
Pronunciation: upper right corner
Formula examples
⌝ is used in a context where marks the upper right corner used to group expressions, denote inner products, intervals, semantics, or specialized mathematical structures.How to type Upper Right Corner
- Windows
- Use Character Map or enter U+231D in a Unicode-aware application.
- macOS
- Open Character Viewer with Control–Command–Space and search by the symbol name.
- Microsoft Word
- In an equation, type \urcorner and press Space when Word supports the command.
- iPhone and iPad
- Copy and paste ⌝, or use a math/LaTeX app. The standard iOS keyboard may not expose every mathematical symbol.
- Android
- Copy and paste ⌝, or use a math keyboard or LaTeX editor. Keyboard layouts vary by device and app.
- Google Docs
- For plain text, paste ⌝ or use Insert → Special characters. For structured math, use the equation editor and verify \urcorner.
- Excel
- Paste ⌝ into a cell or use Insert → Symbol when available. Ordinary cells preserve the character but do not interpret LaTeX commands.
Common mistakes
- Preserve grouping, operator order, and spacing around ⌝; Always pair ⌝ with its matching delimiter and choose scalable LaTeX delimiters for tall fractions, matrices, and nested expressions.
- For plain text, copy ⌝ as U+231D; for structured equations, use \urcorner in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Upper Right Corner.
When to use ⌝
- Use ⌝ in plain text when a Unicode character is appropriate and the destination preserves U+231D.
- Use \urcorner in an equation editor when mathematical spacing or structure matters.
- Define the local meaning when Upper Right Corner is used in basic math, functions operators with a field-specific convention.

Font and compatibility notes
Glyph shape can vary by font. Verify the code point after copying, and prefer LaTeX or MathML for structured equations.
