Why is a *able word used for a class such as Throwable, since this convention is primarily used for interfaces (e.g., Cloneable, Serializable, etc.)?

Answer 1

I don't think there is a convention that says that the able suffix can only be used for interface. Its just a suffix to denote what the class would be capable of.
