Catalytic → It is formed from "cata-" (from Greek "kata", meaning down or against) and "lytic" (from Greek "lytikos", meaning able to loosen or dissolve). The word "catalytic" refers to a substance that causes a reaction by lowering the energy needed to initiate it, effectively 'loosening' the bonds in a chemical reaction.
Think of a substance that 'loosens' or facilitates a reaction ('lytic') by working 'down' or 'against' the energy barrier ('cata-'). This helps you remember that 'catalytic' means something that aids in a chemical reaction.
