Plural of investigation; systematic inquiries or examinations to uncover facts or determine causes.
From Latin 'investigare' (to trace or track), combining 'in-' (into) and 'vestigare' (to track by footprints, from 'vestigium,' footprint). Entered English in the 1400s via Old French.
The root 'vestigium' means footprint—so investigation literally means 'following footprints!' Detectives, scientists, and reporters are all trackers, metaphorically following invisible footprints of evidence.
