hydrolysis

The term 'hydrolysis' is a modern scientific coinage constructed directly from Greek elements to precisely describe a chemical process. It combines hydro-, from the Greek hydōr meaning "water," with -lysis, from the Greek lysis meaning "a loosening or dissolution." The word's literal meaning, "a loosening by water," perfectly captures the essence of the chemical reaction where water molecules cause the cleavage of bonds within a larger compound. This transparent, descriptive construction follows the model of many scientific terms, creating a logical bridge from the ancient literal components to the modern abstract chemical concept.

Structure: hydro (water) + lysis (loosening) - hydro: From Greek hydōr (water). In English, it functions as a combining form meaning "water" or "hydrogen." - lysis: From Greek lysis (a loosening, releasing, dissolution). In English, it functions as a combining form meaning "decomposition" or "breaking down."
