// As a word nerd, I’m always eager to learn a word’s etymology and trace it back to its earliest known origins.

etymology in Context

“A recent Vogue bride, Nicole Amarise, changed her name—as did her husband. ‘Together we opted to create a new one for our new life together,’ she says. ‘We gave ChatGPT information about the etymology of our old surnames, and guided it to generate surname options for us that could relate to our heritages and cultures.’” — Shelby Wax, Vogue, 16 Aug. 2025


Did You Know?

The etymology of etymology itself is relatively straightforward, so we won’t bug you with a lengthy explanation. Etymology ultimately comes from the Greek word etymon, meaning “literal meaning of a word according to its origin.” Etymon in turn comes from etymos, which means “true.” Be careful not to confuse etymology with the similar sounding entomology. Entomon means “insect” in Greek, and entomology is a branch of zoology that deals with insects.
