Mathematical Bold Italic Small Eta Symbol

𝜼 is the mathematical bold italic small eta character (U+1D73C) for math-style text and symbols.

U+1D73C

𝜼 is a Unicode math symbol used to represent a small eta in a bold italic style. It’s commonly needed when matching the typography of equations or mathematical notation.

Mathematical Bold Italic Small Eta Symbol Meaning

𝜼 is “MATHEMATICAL BOLD ITALIC SMALL ETA” with code point U+1D73C (HTML entity 𝜼). Like other math italic/bold variants, it’s meant for consistent mathematical typography—especially when a document, diagram, or typeset output expects a specific glyph shape for eta. Practically, you can use it anywhere plain text must include that exact character: equation labels, variable names, annotated formulas, or styled technical writing. It does not replace regular eta in meaning by itself; the key difference is the specific bold italic glyph that may be required for visual consistency.

Common uses

  • Labeling variables in math formulas where bold italic eta is required
  • Building consistent equation text in design mockups or presentations
  • Typing scientific/technical notes that require exact Unicode glyph matching
  • Annotating diagrams or charts that display mathematical symbols as text
  • Creating math-focused social posts with correct symbol styling
