entomology (noun) (no plural)
1. The branch of zoology that deals with the study of insects: The biology teacher brought in a book about entomology so the students could identify the bug that they found in their classroom.
2. Etymology: from French entomologie (1764), coined from Greek entomon, "insect" + logia, "study of".

Entomon is the neuter form of entomos, "having a notch or cut (at the waist)"; so called by Aristotle in reference to the segmented division of insect bodies.

Scientists who study insects (there are close to a million that can be studied) are called entomologists. Then why aren't they called "insectologists"? Well, they are.

The word insect comes from the Latin word insectum, meaning "cut up" or "divided into segments".

The plural of insectum, namely insecta, is used by scientists as the name of the taxonomic class that insects belong to.

This Latin word was created in order to translate the Greek word for "insect", which is entomon and literally means "cut up" or "divided into segments", and it is the source of the word entomology.

The Greeks coined this term for insects because of the division of insect bodies into three segments, now called the head, thorax, and abdomen.
