 ## Boolean Operators
 
-Boolean operators are used to chain individual expression tree nodes together. There are two boolean operators that can be used: `AND` and `OR`. These boolean operators are accessible via function calls on the expression nodes. Calling these functions generates a new expression tree node which becomes the parent of the nodes on either side of the boolean operator
+Boolean operators are used to chain individual expression tree nodes together. There are two boolean operators that can be used: `AND` and `OR`. These boolean operators are accessible via function calls on the expression nodes. Calling these functions generates a new expression tree op node which becomes the parent of the leaf nodes on either side of the boolean operator
 
 A complex expression tree can be created by calling these functions to chain multiple expression tree nodes together.
