Notes on Meaning
- Important Distinction: In common language, "ngực" means "chest" (of a human or animal). The compound term "ngực sau" has a very specific, technical meaning that is entirely different and refers only to insect anatomy. It does not mean "the back of a chest" or "rear chest" in a general sense.
