Definition & Meaning of "swine"in English

What is the origin of the term "swine" and how is it used?

"Swine" is a slang term used to describe a person regarded as greedy, filthy, or morally contemptible. It comes from the literal pig, an animal long associated with dirt, gluttony, and base behavior, and has been used metaphorically in English since at least the Middle Ages. The term was often applied in religious, moral, or literary contexts to condemn vice or corruption. Today, it remains strongly derogatory and is used in informal, critical, or hostile contexts to insult someone's character, behavior, or cleanliness.
