 Any definition of “morality” in the descriptive sense will need to specify which of the codes put forward by a society or group count as moral. Even in small homogeneous societies that have no written language, distinctions are sometimes made between morality, etiquette, law, and religion. And in larger and more complex societies these distinctions are often sharply marked. So “morality” cannot be taken to refer to every code of conduct put forward by a society.
