Difference Between Entomology and EtymologyThese two ‘-ology’ words are actually vastly different.
Entomology means the study of insects: “The women told us that her brother is famous entomologist who specializes in the life study of bugs.”
Etymology , on the other hand, means the act of tracing the origins, derivations, and developments of words: “Norman Lewis based his book ‘word power made easy’ on the concepts of etymology.”

“Etymology makes it possible to better understand the origin and meanings of words.”
It is important to have an understanding of etymology in order to understand the naming of insects during one’s study of entomology.
An etymologist is someone who knows the difference betweenetymology and entomology.
