Morphology

underactivity = underactive (transparent) = under + active + ity

Formed by adding the noun-forming suffix '-ity' to the clearly analysable adjective 'underactive', so the nominal meaning is directly predictable.

Etymology

The word underactivity comes from the prefix under- meaning 'below' and activity meaning 'action' or 'movement'. So underactivity describes a state where something is less active than normal.
