Surface Forms

hot-water bag singular

Morphology

hot-water + bag

The meaning is directly and transparently derived from the constituents 'hot' + 'water' + 'bag' — a bag that holds hot water for warming. This is a straightforward compositional noun (cf. 'hot-water bottle'/'water bottle') and follows common cross-linguistic logic, so a B1 learner who knows the parts would readily infer the meaning.

Etymology

Hot-water bag shows a simple picture: a bag you fill with hot water, close with a stopper, and put on your feet or stomach to warm you or ease pain. So the name now means a container used 'to warm a bed' or 'to soothe parts of the body'.
