hydrophone = hydro + phone
The structure is clear as a scientific combining-form compound meaning 'water-sound device', but the term is specialized and not fully predictable for an average learner.
Etymology
Hydrophone comes from the parts hydro- meaning 'water' and -phone meaning 'sound', the same -phone you see in telephone and microphone. So a hydrophone is a device for listening to or recording sounds under water.
