@ -1053,6 +1053,19 @@ but they can be used as base contracts::
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``)
::
function(address) external returns (address) foo;
