parasite (English)
Where does "parasite" come from?
The word parasite originates from the Ancient Greek 'parásitos,' which literally meant 'feeding beside' and described someone who dined at another person's table. This term passed through Latin and Middle French, gradually shifting from a descriptor for a dinner guest into a broader label for anyone who relies on others for support. Today, it describes both biological organisms that thrive at a host's expense and people who exploit the efforts of others.
