Etymology

the word 'anhydride' is a modern scientific term constructed from greek components to precisely describe a chemical concept. the prefix 'an-' (from greek, meaning "without") is combined with the root 'hydr-', derived from the greek word 'hydōr' for "water". the suffix '-ide' is a conventional ending in chemical nomenclature, often indicating a class of compounds. thus, the term literally means "a compound without water," which directly and logically reflects its definition as a substance formed by the removal of water from another, such as an acid.
