Etymology

Origin of feces

1425–75; late Middle English < Latin faecēs grounds, dregs, sediment (plural of faex )

Explanation

Feces is a technical word for poop: the brown stuff you excrete from your butt. Everyone makes feces. Also called a bowel movement or stool — plus hundreds of terms in slang — feces is the solid waste material your body makes when you go number two. This isn't the word you'd probably use with your buddies, but it is the right word if you're writing a paper or talking to a teacher. Talking about feces can seem funny, but it's pretty important: if you couldn't make feces, you'd die.
