Mathematical symbol for "has"

Question

Just out of curiosity, I was wondering if there was a symbol for "has" so intead of saying $x \in A$, we could say something like "$A$ has $x$", they both mean the same thing but I was just wondering if there was another way to say it.

Thanks!

Do you mean to say $x$ is an element of $A$, or are you looking for some symbol other than $\in$ to denote 'has'? — Douglas B. Staple, Jun 11 '13 at 02:24
Adding to what @Rahul said, you can also write \owns to generate $\owns$. — Mr Pie, May 17 '18 at 00:31

I believe I have seen $\ni$ used for this purpose. That is, $x\in A \iff A\ni x$

In Unicode it is called "Contains As Member" and is encoded at U+220B. – Lee Sleek Jun 11 '13 at 03:32

The better term to use would be "$A$ includes $x$" instead of "$A$ has $x$", and as Rahul quickly answered, that can be expressed by $A \ni x \iff x\in A$.

Set inclusion is the conventional concept for describing "element - set" relations, which can be discussed with respect to a set which includes an element ($A\ni x$) or an element being "included in" or "belonging to" a set ($x \in A$).

This is analogous to the conventional reference to the relations of set containment, encompassing the relations of $A$ containing another set $B$: $A\supset B$ and of a set B being contained in a set $A$: $B\subset A$.
