What 𝓰 means
Its bold script marks a math identifier; fonts supply its shape.
An identifier is a letter or name for an object in a formula; the formula assigns 𝓰 its particular role. Here, script means a connected, handwritten-looking letterform, while bold means heavier strokes. Older computer character sets already included a small handful of letter-shaped mathematical signs; the mathematical alphabets extend those forms so formulas can distinguish more identifiers by letter style. In mathematics, that style can carry meaning rather than serve as decoration.
Use it in formulas or technical notation; for decorative prose, style ordinary letters instead.
In a formula, reducing it to plain g can erase a distinction.

Questions people ask
1Why can 𝓰 become plain g?
It can happen through compatibility normalization, which reduces 𝓰 to plain g. A math-aware export can preserve the style as separate formatting; a conversion that drops that formatting too can erase the distinction between mathematical identifiers.
