Meaning and usage
Indicates semantic satisfaction or entailment.
Use it to distinguish semantic truth from formal derivation.
Pronunciation: models
Formula examples
\Gamma \models PHow to type Models
- Windows
- Open Character Map and search by name or Unicode U+22A8.
- macOS
- Open Character Viewer with Control–Command–Space and search by the symbol name.
- Microsoft Word
- In an equation, type \models 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 \models.
- Excel
- Paste ⊨ into a cell or use Insert → Symbol when available. Ordinary cells preserve the character but do not interpret LaTeX commands.
Common mistakes
- Define the logical convention before using ⊨; proof, programming, and Boolean-algebra sources may assign different precedence or direction.
- For plain text, copy ⊨ as U+22A8; for structured equations, use \models in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Models.
When to use ⊨
- Use ⊨ in plain text when a Unicode character is appropriate and the destination preserves U+22A8.
- Use \models in an equation editor when mathematical spacing or structure matters.
- Define the local meaning when Models is used in logic with a field-specific convention.
Look-alikes and related characters
- ∀ — For All
- ∃ — There Exists
- ∧ — Logical And
Font and compatibility notes
Glyph shape can vary by font. Verify the code point after copying, and prefer LaTeX or MathML for structured equations.
