The word faeces is the plural of the Latin word fæx meaning "dregs". There is no singular form in the English language, making it a plurale tantum.
There are many colloquial terms for feces, of which some are considered profanity (such as shit) while others (such as poo, poop, number two, deuce, doodoo, dookie and doody) are not. Terms such as dung, scat, spoor and droppings are normally used to refer to animal feces.
Stool is a common term normally used in reference to human feces. For example, in medicine to diagnose the presence or absence of a medical condition, a stool sample is sometimes requested for testing purposes.[2] The term "stool" can also be used for that of non-human species.

The distinctive odor of feces is due to bacterial action. Gut flora produce compounds such as indole, skatole, and thiols (sulfur-containing compounds), as well as the inorganic gas hydrogen sulfide. These are the same compounds that are responsible for the odor of flatulence. Consumption of foods with spices may result in the spices being undigested and adding to the odor of feces. The perceived bad odor of feces has been hypothesized to be a deterrent for humans, as consuming or touching it may result in sickness or infection.Of course, human perception of the odor is a subjective matter; an animal that eats feces may be attracted to its odor.

Human feces may be used as fertilizer (See also: Humanure) in the form of biosolids (treated sewage sludge). The feces of animals are often used as fertilizer; see manure and guano. Some animal feces, especially those of camel, bison and cattle, is used as fuel when dried out.Animal dung, besides being used as fuel, is occasionally used as a cement to make adobe mudbrick huts or even in throwing sports such as cow pat throwing or camel dung throwing contests.[9] Kopi Luwak (pronounced [ˈkopi ˈlu.aʔ]), or Civet coffee, is coffee made from coffee berries which have been eaten by and passed through the digestive tract of the Asian Palm Civet (Paradoxurus hermaphroditus).

Dog feces were used in the tanning process of leather during the Victorian era. Collected dog feces were mixed with water to form a substance known as "bate". Enzymes in the dog feces helped to relax the fibrous structure of the hide before the final stages of tanning.
