research

n. a systematic investigation to establish facts or principles

The word "research" originates from the 16th-century French term recherche ("to seek closely"), combining the prefix re- (indicating repetition) and chercher ("to search"). The morpheme re- reinforces the idea of repeated or thorough examination, while search retains its core meaning of exploration. This reflects the methodical nature of research as an iterative process of inquiry.
