Morphology

hyperdactyly = dactyly (semi-transparent) = hyper + dactyl + y

The prefix hyper- added to 'dactyly' suggests an excess condition, but the exact medical meaning remains specialized.

Etymology

The word hyperdactyly comes from Greek parts hyper- meaning 'over' or 'too many' and dactyl meaning 'finger'. You can see the same hyper- in hyperactive, which means 'very active', so hyperdactyly is the condition of having 'too many' fingers or toes.
