U+1D552

𝕒, known as Mathematical Double-Struck Small A, is a Unicode character used in mathematical typesetting. It’s especially useful when you need a distinct β€œdouble-struck” style for an italic lowercase A. Below you’ll find copy-friendly forms and practical ways to use it in text and code.

Mathematical Double-struck Small A Symbol Meaning

𝕒 (Unicode U+1D552) is a double-struck (blackboard bold–style) lowercase β€œa” used in math and related technical writing. This typographic form is commonly used to distinguish specific sets, constants, or named objects from ordinary italic variables. Depending on the context and the document’s notation conventions, it may represent something like a particular algebraic structure, a designated variable, or an element belonging to a named collection. Because it’s a distinct Unicode character (not just a font effect), it remains consistent across systems that support the glyph, making it convenient for copy/paste into documents, websites, and code.

Common uses

  • β€’Mathematical notation in papers and reports where a double-struck lowercase a is required
  • β€’Typing variables in LaTeX-like styled text when you want a Unicode glyph without extra packages
  • β€’Designing posters or slides that include consistent, readable mathematical letter styles
  • β€’Creating technical social posts or documentation that needs a specific symbol look
  • β€’Building UI text in developer tools or dashboards that display math-style variables
