excrement

While not a pleasant topic, excrement refers to solid waste that leaves the body, especially human feces or animal droppings. It is a more formal and clinical word than "poop," and it usually appears in medical, scientific, or official writing. You would not often use it in casual conversation, but you might see it in a report about testing animal excrement to learn about diet or disease.

The word comes from the Latin excrementum, meaning "something sifted out" or removed. In modern English, it mainly refers to feces, not just any kind of waste. It can also be used in a figurative way for something seen as filthy, worthless, or offensive, but that use is much less common than the literal one.

Excrement is a formal word for solid waste discharged from the body, especially from the digestive system of humans and other animals. In everyday English, people usually say "poop," "feces," or "droppings" instead, but excrement is common in medical, scientific, legal, and technical contexts. A veterinarian may examine a dog's excrement for signs of parasites, and a wildlife researcher may study animal excrement to learn what the animals have been eating.

The word has a clear clinical tone, so you are much more likely to find it in a lab report than in casual speech. It lets people discuss an unpleasant subject in a neutral and precise way. In fields such as veterinary medicine, environmental science, sanitation, and archaeology, excrement can be important evidence. For example, fossilized excrement, called coprolites, can tell researchers about the diet and health of ancient animals.

The meaning is mostly literal, but the word can also be used as an insult or metaphor. Someone might call a terrible piece of writing "literary excrement" to show extreme contempt. In that kind of use, the idea is not about biology anymore, but about something being disgusting, worthless, or deeply offensive.

Historically, the term was sometimes used more broadly for matter that had been cast off or left behind, but that sense is rare now. Today, when people use excrement, they usually mean feces in a formal or technical way. It remains a precise word for a basic biological fact, even if it is not one people usually choose at the dinner table.
