MathML token

<mi>

Use ℓ as an identifier or variable name, and define it before the first calculation. In MathML this role normally uses the mi token rather than an operator token.

  • ⃗ — Combining Vector Arrow
  • ℂ — Complex Numbers
  • ℍ — Quaternions

How to type Script Small L

Windows
Use Character Map or enter U+2113 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 \ell and press Space when Word supports the command.
iPhone and iPad
Copy and paste ℓ, or use a math/LaTeX app. The standard iOS keyboard may not expose every mathematical symbol.
Android
Copy and paste ℓ, or use a math keyboard or LaTeX editor. Keyboard layouts vary by device and app.
Google Docs
For plain text, paste ℓ or use Insert → Special characters. For structured math, use the equation editor and verify \ell.
Excel
Paste ℓ 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 ℓ; case and mathematical alphabet style can identify different quantities.
  • For plain text, copy ℓ as U+2113; for structured equations, use \ell in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Script Small L.

When to use ℓ

  • Use ℓ in plain text when a Unicode character is appropriate and the destination preserves U+2113.
  • Use \ell in an equation editor when mathematical spacing or structure matters.
  • Define the local meaning when Script Small L is used in math alphanumeric, physics with a field-specific convention.

Look-alikes and related characters

  • ⃗ — Combining Vector Arrow
  • ℂ — Complex Numbers
  • ℍ — Quaternions

Font and compatibility notes

Font coverage varies; verify the code point and destination rendering before publication.
