The symbol $\subset$ stands for subset. So, $A \subset B$ means that A is a subset of B.

This means that every element in A is also an element of B, while the opposite is not necessarily true: there can be elements of B that are not elements of A.

For example, if you consider the sets

$A = \{ \text{US Capitals} \},\ \ B = \{ \text{US Cities} \}$

You can see that A is a subset of B: every Capitol is a city, but most cities aren't capitols.
