Morphology

aquifer = aqua (semi-transparent) = aqua + fer

The form combines the Latin combining form 'aqua' (water), which is recognizable, with '-fer' ('bearing') which is not productive in modern English; learners may infer 'water-bearing' only if they recognise 'aqua'.

Etymology

The word aquifer comes from the Latin parts aqua 'water' and fer 'to carry'. You can see fer in words like ferry or transfer, which are about carrying. So think of an aquifer as a 'water-carrier' underground, a layer of rock or sand that holds and moves groundwater to wells and springs.
