Mathematical Bold Script Small H 𝓱

Visual Description: The character appears as a bold, cursive h with strong vertical strokes. It has a flowing loop at the top and a compact tail, giving it a formal, handwritten feel. In digital math fonts, it resembles the bold script style used for emphasis. It stands out in formulas.

Meaning & Usage: It signals a special object rather than a plain variable. In math, bold script letters often distinguish objects like functions, sets, or marked constants. They are used alongside regular letters to avoid confusion and to guide readers through equations and comparisons. Tools may support quick insertions.

Historical Background: In typesetting and digital fonts, bold script variants were adopted to separate shapes from ordinary text. Unicode and font designers grouped these symbols in a dedicated block for mathematical notation. The idea is to provide stylistic markers that help organize complex equations without altering the underlying meaning.

Practical Use: In formulas, you might see h used as a distinctive object; a calculator or math editor can switch to bold script with a single control. Quick UI buttons or shortcuts enable formatting, enabling rapid comparisons or formatting changes as you build a larger expression.
