Etymology

Origin of entomologist

First recorded in 1770–80; entomolog(y) ( def. ) + -ist ( def. )

Explanation

If you are crazy about spiders, ants, beetles, and other creepy-crawlies, you might aspire to be an entomologist someday — a scientist who studies insects. An entomologist is a specific type of zoologist, or animal scientist. While other zoologists might focus on mammals or reptiles, entomologists are fascinated with the most prolific organisms on earth — insects. Some entomologists classify and study species, while others are certified to be pest control experts, helping people battle bugs like cockroaches and termites in their homes. The Greek word entomon, or "insect," is at the root of entomologist.
