Here's how 'parasite' went from a laughing matter to a serious biological threat
This article explores the etymological evolution of the word 'parasite' from its origins as a comedic stock character in ancient Greece to its modern biological and derogatory usage. It highlights how the term shifted from a social role to a scientific classification.
Why it matters
Understanding the history of language helps clarify how modern scientific terms carry cultural baggage and historical context.
Cyclospora and Christopher Nolan's nearly three hour adaptation of The Odyssey have something in common — parasites.
For Cyclospora , that connection is easy to make. The microscopic parasite causes cyclosporiasis, the intestinal illness that has sickened thousands of Americans .
And while Odysseus does not face an intestinal parasite on his long journey home — though his voyage was still quite miserable — he encountered another kind when he returned to Ithaca. Those were the suitors who had taken over his home, courting his wife Penelope. They embodied a popular character trope in ancient Greek writing: one that originated as a form of comic relief.
As part of NPR's "Word of the Week" series , we're explaining how the word "parasite" started as a joke and became anything but funny.
