Usage

Where does pig come from? Let’s start with a little swine quiz: what’s the difference between a pig and a hog? In the barnyard, a pig is a young domestic hog. Generally speaking, a pig weighs less than 120 pounds, the hog is much heavier. Like the word dog, forms of the word pig and hog are found in Old English, however their ultimate origin is obscure. Etymologists think that final -g in dog, pig, and hog are related, though. Discover more everyday words with unknown roots in our slideshow, “‘Dog,’ ‘Boy,’ And Other Words That We Don’t Know Where They Came From."

Why do we raise pigs but eat pork? Same goes for cow vs. beef. It is because of the influence of French (and its higher social status) in Middle English. Via French, pork comes from the Latin porcus, "pig, hog."

Now that you know how pigs got their name, why not find out how some of our other most beloved pets got theirs in the slideshow: "Where Do The Words For Our Pets Come From?"

Explanation

Oink. A pig is a farm animal with a curly tail, hooves, floppy ears, and a flat snout for rooting. Cooked pig is popular, but the pig from Charlotte’s Web is saved from becoming bacon by a crafty spider. Pigs are omnivores — they eat both plants and meat — and on small farms, they're fed kitchen leftovers as well as their basic diet. Their dining habits have given pigs the reputation of being greedy, and led to the informal use of pig to mean "greedy person," and pig out to mean "eat voraciously." Another colloquial meaning of pig, one that's been considered derogatory since it was coined in the nineteenth century, is "police officer."
