Morphology

water + mat

The meaning 'a mat for use on water' is directly and compositionally derived from 'water' (the liquid) + 'mat' (a piece of material or rug), following a standard noun-noun compound pattern. This is a transparent, cross-linguistically common concept so a B1 learner who knows the ordinary sense of 'mat' will readily infer the MWE; only possible confusion arises if a learner knows only the rarer sense of 'mat' (tangled hair).

Etymology

The noun water mat comes from the plant's habit of growing in thick, flat patches that lie across ponds and streams like a mat on the water. So the name refers to an aquatic herb that makes a flat, mat-like cover on the water.
