U+2208
The symbol ∈ is commonly read as “is an element of.” It’s frequently used in math and logic to state set membership. You can copy it directly or use its Unicode code point.
Element Of Symbol Meaning
∈ (Unicode U+2208) is read as “is an element of” or “belongs to” when working with sets. For example, you might write that a number x is an element of a set S, meaning x is one of the members of S. In formal logic and mathematics, ∈ helps distinguish membership from other relationships like subset (⊆) or equality (=). Many text and typesetting systems support it as a standard mathematical symbol, making it useful for equations, proofs, and educational materials.
Common uses
- •Expressing that an item belongs to a set, such as x ∈ S
- •Writing membership conditions in math problems and solutions
- •Describing logical statements about which options are included in a collection
- •Annotating vectors, functions, or domains with elements that are allowed or included
- •Building clear notation in educational slides, worksheets, and documentation
