Mathematical Sans-serif Bold Small Delta Symbol
𝝳 is a Unicode math symbol: mathematical sans-serif bold small delta.
U+1D773
𝝳 is a Unicode character from the mathematical sans-serif bold set. You’ll mainly see it in math-style typography where a specific “delta” variant is needed.
Mathematical Sans-serif Bold Small Delta Symbol Meaning
𝝳 is “MATHEMATICAL SANS-SERIF BOLD SMALL DELTA” (Unicode U+1D773). It’s a stylized lowercase delta used in mathematical notation and typesetting systems that rely on specialized Unicode math letters. Compared with the more common Greek delta (Δ/δ), this character has a sans-serif, bold, and small (lowercase-form) appearance, making it useful when authors need consistent visual styling across variables. Since it is part of Unicode’s mathematical alphanumeric symbols block, it’s typically used in editors, publishing workflows, and code contexts where exact Unicode characters must be preserved.
Common uses
- •Math writing in plain text where you need a specific bold sans-serif delta variant
- •Designing consistent notation styles in posters, slides, or documentation
- •Copy/pasting into LaTeX-like or Unicode math-friendly editors to match a template
- •Labeling variables in technical diagrams that use Unicode characters
- •Creating social or educational posts that reference a specific symbol variant
