Morphology

mud + flat

The noun is directly and compositionally built from 'mud' (wet, sticky earth) + 'flat' (level area), so a learner who knows both words can infer it refers to a level area of mud. The specific coastal/tidal detail (covered at high tide, exposed at low tide) is extra encyclopedic information but does not prevent the core meaning being transparently understood; this compound pattern is cross-linguistically common.

Etymology

Mud flat names a wide, flat area of mud near the sea. These places are 'covered at high tide' and 'exposed at low tide', so the name means the flat muddy land along the shore.
