Morphology

acuity = acute (transparent) = acute + ity

Formed by the productive suffix '-ity' from the adjective 'acute', so the meaning 'sharpness of mind' is directly derived despite a small orthographic change.

Etymology

The word acuity comes from the old Latin word acer meaning 'sharp', and is the same root as acute. So acuity of mind means 'sharp' thinking that is quick and clear.
