Morphology

incidence = incident (semi-transparent) = incident + ence

The word is clearly built on the recognizable base 'incident', but the statistical sense of frequency or rate of occurrence is specialized and not fully predictable from the base alone.

Etymology

The word incidence comes from an old Latin word incidere, which meant 'to fall on' and is made of in- 'on' and cadere 'to fall'. It shares the same root as the common word accident, which also has the idea of something that 'falls' on you, so incidence means how often something happens in a group.
