Intersection With Dot Symbol

The ⩀ symbol denotes an intersection indicated with a dot, commonly used in math and diagram labeling.

U+2A40

⩀ (intersection with dot) is a Unicode math symbol used to mark a specific kind of intersection. It can appear in set notation, logic, and annotated diagrams where a highlighted overlap is helpful. Below you’ll find its meaning and practical copy/paste variations.

Intersection With Dot Symbol Meaning

The symbol ⩀ is named “Intersection with dot” and corresponds to Unicode U+2A40. In mathematical writing, it’s used to represent the intersection of two entities with an added visual cue (a dot), helping readers distinguish it from other intersection styles. Depending on the context, it may be used in set-related notation (e.g., emphasizing a shared element) or in logic/diagram conventions where an overlap point needs clearer emphasis. When typing or designing with this character, it’s often chosen for clarity in text-based formulas, technical annotations, and typography where the “dotted” intersection look is part of the intended notation.

Common uses

  • Marking the overlap of two sets in typed mathematical notes
  • Highlighting an intersection point in logic or Venn-style diagram captions
  • Labeling shared elements in technical documentation and specs
  • Formatting custom equations or notation in math/physics writing
  • Adding a dotted intersection marker in diagram-based learning materials

Examples

⩀ Intersection with dot

  • A ⩀ B denotes the shared elements of the two sets.
  • The diagram shows C ⩀ D at the highlighted overlap region.
  • In our notation, ⩀ marks where conditions intersect.
  • We use ⩀ to emphasize the dotted intersection point on the chart.
  • Let x ∈ (E ⩀ F) represent the common candidates.
