Notes on Meaning
  • The word "kí sinh trùng" is a compound noun formed from "kí sinh" (to live parasitically) and "trùng" (a microorganism, germ, or worm). It specifically refers to the parasitic organism itself.
  • It is a scientific and medical term but is widely understood in general usage. It does not carry the additional figurative meaning of a person who lives off others (like the English "parasite" sometimes does); for that meaning, Vietnamese uses words like "kẻ ăn bám".
