The Vietnamese word "giun sán" refers to "parasitical worms" in English. These are worms that live in or on a host organism and can cause harm to that host. They are often found in the intestines of animals and humans, where they can feed off nutrients and cause various health issues.
In more advanced discussions, "giun sán" can be used in technical contexts, such as: - Discussing specific types of parasitic worms, like "giun đũa" (roundworm) or "sán lá" (liver fluke). - Talking about prevention methods, such as deworming treatments or the importance of sanitation.
While "giun sán" primarily refers to parasitic worms, it can sometimes be used metaphorically to describe something that is harmful or a nuisance, similar to how we might say "a pest" in English.
