U+209B_sₛₛ<mi>ₛ</mi>Semantic identity and intent
Characters to distinguish
- ² — Superscript Two
- ₁ — Subscript One
- ⁰ — Superscript Zero
Use ₛ in the right format
Meaning and usage
Represents subscript s as a standalone Unicode character for compact linear notation.
Use ₛ only when a plain-text destination cannot render structured subscripts or superscripts; use LaTeX _s for full equations.
Pronunciation: subscript s
Formula examples
ₛ is used in a context where represents subscript s as a standalone Unicode character for compact linear notation.How to type Subscript S
- Windows
- Use Character Map or enter U+209B 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 _s and press Space when Word supports the command.
- iPhone and iPad
- Copy and paste ₛ, or use a math/LaTeX app. The standard iOS keyboard may not expose every mathematical symbol.
- Android
- Copy and paste ₛ, or use a math keyboard or LaTeX editor. Keyboard layouts vary by device and app.
- Google Docs
- For plain text, paste ₛ or use Insert → Special characters. For structured math, use the equation editor and verify _s.
- Excel
- Paste ₛ into a cell or use Insert → Symbol when available. Ordinary cells preserve the character but do not interpret LaTeX commands.
Common mistakes
- Do not substitute a visually similar Latin or differently styled character for ₛ; case and mathematical alphabet style can identify different quantities.
- For plain text, copy ₛ as U+209B; for structured equations, use _s in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Subscript S.
When to use ₛ
- Use ₛ in plain text when a Unicode character is appropriate and the destination preserves U+209B.
- Use _s in an equation editor when mathematical spacing or structure matters.
- Define the local meaning when Subscript S is used in super sub, math alphanumeric with a field-specific convention.
