Etymology

Origin of research

First recorded in 1570–80; (verb) from Middle French recercher “to seek,” Old French, equivalent to re- re- + cercher search; (noun) from Middle French recerche


Explanation

In their spare time, teenagers LOVE doing extra research, by investigating the facts of a certain subject and studying and recording what they learn. And if you believe that, you need to do more research on the habits of teenagers. Research comes from the Old French word recercher, meaning "seek out," or "search closely." When you do research, you are searching for knowledge and facts. Although you write plenty of research papers in college, on anything from the Industrial Revolution to the meaning behind a fur-lined teacup, the term is often used when talking about science, because scientists use step-by-step research to prove what is true, or not true, in their line of work.
