precursor
의미: A person or thing that comes before another of the same kind; a forerunner or predecessor.
Precursor is used in science, history, and general discourse to describe something that comes before and often paves the way for something else. In chemistry, a precursor is a compound that participates in a chemical reaction to produce another compound. In history and culture, it describes earlier forms, ideas, or movements that anticipated later developments. Common collocations include 'precursor to,' 'chemical precursor,' and 'early precursor.'
