faeces

This term is the primary technical and medical designation for bowel waste. It carries a clinical, sterile tone and is used almost exclusively in scientific, veterinary, or medical reports to avoid the colloquial or vulgar connotations associated with common synonyms.

Grammatically, the word is treated as a plural noun (derived from Latin), meaning it typically takes a plural verb. While it refers to a singular mass of waste, it functions similarly to words like "viscera" or "data" in formal contexts.
