- ⊇ — Superset Of or Equal To
Use ⊉ in the right format
Meaning and usage
States that the first set does not contain every element of the second set.
Use it as the reverse-direction counterpart of not-subset-or-equal.
Pronunciation: not a superset of or equal to
Formula examples
A⊉BHow to type Not a Superset Of or Equal To
- Windows
- Use Character Map or enter U+2289 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 \nsupseteq 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 \nsupseteq.
- Excel
- Paste ⊉ into a cell or use Insert → Symbol when available. Ordinary cells preserve the character but do not interpret LaTeX commands.
Common mistakes
- Check whether ⊉ allows equality in the convention you are using; strict and non-strict subset symbols are not interchangeable.
- For plain text, copy ⊉ as U+2289; for structured equations, use \nsupseteq in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Not a Superset Of or Equal To.
When to use ⊉
- Use ⊉ in plain text when a Unicode character is appropriate and the destination preserves U+2289.
- Use \nsupseteq in an equation editor when mathematical spacing or structure matters.
- Define the local meaning when Not a Superset Of or Equal To is used in set theory with a field-specific convention.
Look-alikes and related characters
