means A parasitic worm (like a tapeworm, roundworm, or fluke) that lives inside a host organism, often in the intestines.

from From Greek 'helmins' (ἕλμινς), meaning simply 'worm' or 'intestinal worm.' The Greeks used it broadly for creeping, wriggling things, and physicians like those in the Hippocratic tradition used it specifically for intestinal parasites. The word passed quietly into scientific Latin and then English as 'helminth,' staying almost unchanged for over two thousand years — proof that some ancient complaints about unwelcome gut guests never needed updating.
