Inheritance is one way of describing it but I don't think the term really fits. An object is composed of multiple components, and the composition can be changed at runtime. Saying that the object inherits from multiple base "classes" seems like it just makes the concept less clear. Some languages have class-based systems with inheritance: one class inherits from another, and methods implemented in the superclass can be used in the subclass. Some languages have prototype-based systems with inheritance: one object inherits from another, and methods implemented in the prototype can be used in the object. Component-based systems don't really fit my mental model of inheritance here.
