swine

Originally, swine simply meant "pig" or "pigs." That literal meaning still appears in farming, older writing, and set phrases such as "pearls before swine." But in everyday modern English, the word often sounds harsh and insulting. If you call someone "a swine," you mean they are nasty, selfish, dirty, or morally unpleasant. It is a strong, old-fashioned insult, so it is rarely used in a friendly or neutral way.

The word swine began as a straightforward name for pigs, especially pigs considered as a group. That literal meaning is still used in farming, hunting, older texts, and familiar expressions such as "pearls before swine." In that older and more literal sense, it refers to members of the pig family, including domestic pigs and sometimes wild pigs.

Over time, the word also developed a strongly negative meaning when applied to people. To call someone "a swine" is to say that they are disgusting, cruel, selfish, or morally bad. It is an offensive insult, and it often sounds old-fashioned, dramatic, or literary rather than casual. Even so, the insult is clear and can sound quite severe.

One useful detail is that swine can work as either a singular or plural noun, depending on the context. A writer may speak of "swine" meaning several pigs, but a speaker may also call one person "a swine." So the word carries both a plain animal meaning and a sharp human insult. In modern English, the insulted-person sense is usually the more emotionally charged one, so the word should be used with care.
