Morphology

undertow = tow (semi-transparent) = under + tow

The components 'under' + 'tow' together convey a pulling current beneath the surface, but learners may not immediately link 'tow' (pull) to a water current without context.

Etymology

The word undertow comes from under 'below' and tow 'pull', like a tow truck that pulls a car. So an undertow is a hidden, strong current under the water that can pull swimmers out to sea.
