You can, as Kent said, override the method to do nothing. Some languages, like Eifell offer better support for that than others. But there is a danger in removing methods too. By doing so you break one of the fundamental principles of inheritence: that everywhere that you use the superclass you can use the sub class. If you remove the fly() method from your subclass of birds code like this will break: birds = [ aSwallow, anOstrich, anEmu, anEagle] for bird in birds: bird.fly() Whereas if you simply make fly a null method you can still call it but nothing happens - a lot safer... But conceptually the problem (and it is common) is that bird has a fly() method when not all birds can fly - the object model is broken at a high level of abstraction.
