U+2092_oₒₒ<mi>ₒ</mi>Semantic identity and intent
Characters to distinguish
- ² — Superscript Two
- ₁ — Subscript One
- ⁰ — Superscript Zero
Use ₒ in the right format
Meaning and usage
Represents subscript o as a standalone Unicode character for compact linear notation.
Use ₒ only when a plain-text destination cannot render structured subscripts or superscripts; use LaTeX _o for full equations.
Pronunciation: subscript o
Formula examples
ₒ is used in a context where represents subscript o as a standalone Unicode character for compact linear notation.How to type Subscript O
- Windows
- Use Character Map or enter U+2092 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 _o and press Space when Word supports the command.
- iPhone and iPad
- Copy and paste ₒ, or use a math/LaTeX app. The standard iOS keyboard may not expose every mathematical symbol.
- Android
- Copy and paste ₒ, or use a math keyboard or LaTeX editor. Keyboard layouts vary by device and app.
- Google Docs
- For plain text, paste ₒ or use Insert → Special characters. For structured math, use the equation editor and verify _o.
- Excel
- Paste ₒ 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 ₒ; case and mathematical alphabet style can identify different quantities.
- For plain text, copy ₒ as U+2092; for structured equations, use _o in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Subscript O.
When to use ₒ
- Use ₒ in plain text when a Unicode character is appropriate and the destination preserves U+2092.
- Use _o in an equation editor when mathematical spacing or structure matters.
- Define the local meaning when Subscript O is used in super sub, math alphanumeric with a field-specific convention.
