Root Explanation

Catalyse is derived from the Greek word "catalusis" (meaning dissolution or loosening) and the suffix "-ze" (used to form verbs). The term refers to the process of causing a reaction to occur more quickly or easily, essentially 'loosening' the bonds in a chemical reaction.

Memory Tip

Think of 'loosening' ('catalusis') to remember that 'catalyse' means to speed up a chemical reaction.
