Morphology

entrain = train (transparent) = en + train

The sense 'to carry or transport along with a moving fluid' is a direct, literal extension of 'pull along' and is likely inferable from en- + train.

Etymology

Entrain comes from French parts en- 'in' and train 'to pull', the same root as tractor. So when water or wind 'entrains' sand or dust, it is 'pulling' those particles along in the flow.
