👤 Eponyms
An eponym is a word that comes from a person’s name. Some of the most ordinary English words began as references to real people: the sandwich, the boycott, the diesel engine, even the cardigan and sideburns. Over time the connection to the original person often fades, and the word simply becomes part of everyday vocabulary.
The entries below give the person behind each word, a clear modern meaning, and a natural example. Knowing the origin makes the word more memorable and sometimes explains its exact flavor.
