History for insect
The distinct parts into which insects’ bodies are divided—head, thorax, and abdomen—inspired the Greek name used for them by the philosopher Aristotle: entomon, the “notched” or “segmented” animal. (Entomon is a noun derived from the verb entemnein, “to cut up” or “to cut into.”) The Romans used insectum, a literal translation of Greek entomon, as their name for the creatures, and this Latin word has provided us with the ordinary English word for insects.
