Mathematical Italic Small Delta Symbol
𝛿 is the Mathematical Italic Small Delta character used as a styled “delta” in math notation.
U+1D6FF
𝛿 (U+1D6FF) is a Unicode character commonly used to represent a small delta in mathematical text. Because it is styled as “mathematical italic,” it often appears in typeset formulas, headings, and symbol-heavy UI. You can copy it directly or use the provided HTML/CSS/JavaScript escapes.
Mathematical Italic Small Delta Symbol Meaning
The symbol 𝛿 is the Unicode character named “MATHEMATICAL ITALIC SMALL DELTA” (U+1D6FF). It is a typographic variant of the Greek letter delta rendered in a mathematical italic style and lowercase/small form. In practice, it functions like a delta symbol in math-writing contexts where the italic math look matters, such as labeling changes (Δ-like notation), referencing variables in equations, or matching the visual style of other mathematical italic symbols. Use it when you specifically want this Unicode character rather than the plain Greek delta (δ) or other delta variants.
Common uses
- •Labeling variables or parameters in math-heavy documents and slides
- •Writing equation text where a mathematical-italic delta style is required
- •Designing UI labels/icons for STEM tools that use Unicode math symbols
- •Creating consistent typographic symbol sets in technical typography
- •Formatting posts or diagrams that include styled Greek symbols
