⊃
⊃ Superset Symbol
The superset sign (⊃) says a set contains another entirely — B ⊃ A is the mirror image of A ⊂ B.
Also known as: superset symbol, superset latex, contains symbol set, superset sign.

How to type ⊃ (Superset Symbol)
WindowsAlt + 8835
Alt + 8835 works in apps that accept decimal-Unicode Alt input. In Word type 2283 then Alt + X; elsewhere press Win + . (period) and search “superset”.
Mac
No default keystroke. Open Character Viewer (Control + Cmd + Space) and search “superset of”, or copy ⊃ above.
Microsoft Word2283, Alt + X
Type 2283, then press Alt + X to convert it to ⊃ (2287 then Alt + X gives ⊇).
Google Docs
Insert → Special characters, then search “superset” — or inside an Equation type \supset.
LaTeX\supset
Use \supset in math mode; \supseteq gives ⊇ and \supsetneq gives ⊋.
Usage
- B ⊃ A means B contains every element of A — the same claim as A ⊂ B, read from the larger set.
- As with ⊂, ⊇ is unambiguous (“superset or equal”) while ⊃ is convention-dependent: some authors mean proper superset, some do not. Write ⊇ or ⊋ when the distinction matters.
- ⊃ has a second, unrelated life in older logic texts, where A ⊃ B is material implication — what most modern writing spells A → B. Context decides which one you are reading, which is a good reason to prefer → for implication.
- In LaTeX, \supset is a relation and typesets with space either side; do not use a stray > instead, which is a different relation entirely.
