Hello. Your question is incomplete, which makes it impossible for it to be answered. However, I believe your question is related to the terms used by Prospero and Miranda to refer to Caliban. These terms express the imperialist view of Europeans in relation to other peoples. As you can see, Caliban is treated as something impure, evil, uncomfortable and that must be fought, something created by the devil and with a disgusting appearance. It was common for European nations to have this kind of thoughts with the native populations of the newly discovered lands, which they saw as inferior, ill-educated, savage, disgusting and diabolical people, while European cultures were seen as superior and beneficial.
