Synonym discussion

Sense: noun/1

Researcher is the broadest of these four terms and applies to anyone doing systematic investigation in any field, from medicine to linguistics to market trends. A scientist is a researcher who works specifically in the natural sciences — biology, chemistry, physics — and typically uses controlled experiments. A scholar is a researcher in the humanities or social sciences, closely tied to reading, writing, and university debate; the word feels more formal and less practical. An investigator focuses on discovering facts about a specific event or situation, often in legal or journalistic contexts — think 'police investigator' or 'fraud investigator.' An academic is a researcher employed by a university or college; the term emphasizes the institutional setting rather than the method. For example, a person studying dolphin communication could be called a researcher (broadest), a marine scientist (narrower field), or an academic (if she works at a university), but not an investigator (unless she is solving a specific dolphin-related crime).

Etymology

FrenchEnglish

Researcher comes from the verb research, which entered English in the late 1500s from Middle French recercher — 'to search closely' (from re- 'again, intensively' + cercher 'to search'). The suffix -er ('someone who does') was added to form the noun. The modern sense of systematic academic or scientific investigation became dominant in the 1800s as universities and laboratories grew.
