Morphology

stuffing + nut

The compound is logically built from 'stuffing' + 'nut' so learners can guess it is a nut related to stuffing, but the technical sense of 'stuffing' (packing/gland packing) and the specific function (compressing packing to prevent leakage) are domain-specific and not derivable from the common B1 sense of 'stuffing' (pillow filling). Because partial inference is possible but precise meaning requires technical knowledge or prior exposure, this is best classified as semi-transparent.

Etymology

Stuffing nut is a metal nut that you tighten to press the soft stuffing around a moving shaft, like squeezing a ring to stop oil or water from escaping. That's why it means a nut used to compress packing and 'prevent leaks'.
