U+22D0\Subset⋐⋐<mo>⋐</mo>Semantic identity and intent
Characters to distinguish
- ∈ — Element Of
- ∉ — Not an Element Of
- ⊂ — Subset / Proper Subset
Use ⋐ in the right format
Meaning and usage
Represents the double subset, a specialized mathematical operator or relation whose exact definition depends on context.
Define the operands and result type when first using ⋐; specialized operator symbols should not be treated as ordinary multiplication or punctuation.
Pronunciation: double subset
Formula examples
⋐ is used in a context where represents the double subset, a specialized mathematical operator or relation whose exact definition depends on context.How to type Double Subset
- Windows
- Use Character Map or enter U+22D0 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 \Subset 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 \Subset.
- 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+22D0; for structured equations, use \Subset in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Double Subset.
When to use ⋐
- Use ⋐ in plain text when a Unicode character is appropriate and the destination preserves U+22D0.
- Use \Subset in an equation editor when mathematical spacing or structure matters.
- Define the local meaning when Double Subset is used in set theory, topology with a field-specific convention.
Look-alikes and related characters
- ∈ — Element Of
- ∉ — Not an Element Of
- ⊂ — Subset / Proper Subset
Font and compatibility notes
Glyph shape can vary by font. Verify the code point after copying, and prefer LaTeX or MathML for structured equations.
