A salt or compound formed by the reaction of copper oxide with an acid; a chemical containing copper.
From Latin 'cuprum' (copper) plus the chemical suffix '-ate', indicating a compound or salt. This follows standard chemistry nomenclature.
Chemistry suffix '-ate' tells you something important: it marks salts and compounds, so 'cuprate' immediately signals to chemists 'this is copper combined with something else'—a shorthand that makes complex chemistry readable.
