If a contract inherits from an abstract contract and does not implement all non-implemented functions by overriding, it will itself be abstract.
+Note that an abstract function is different from a :ref:`Function Type <function-types>` even though their syntax looks very similar.
+
+Example of Abstract function (a function declaration)
+::
+
+ function foo(address) external returns (address);
+
+Example of a Function Type (a variable declaration, where the variable is of type ``function``)
