excrement

The word excrement originates from the Latin verb excernere, meaning "to sift out, separate, or discharge". This verb itself is composed of the prefix ex- ("out") and the root cernere ("to sift, decide"). The literal sense was of the body sifting out and expelling waste. The noun excrementum referred to that which is sifted or discharged. Over time, the meaning narrowed specifically to the waste matter expelled from the bowels, while the related word "secretion" retained the broader sense of a separated substance. The core logic of separation and expulsion remains embedded in the modern term.
