investigate

investigate: [16] To investigate something is etymologically to look for traces, or ‘vestiges’, of it. The word comes from Latin investīgāre ‘search into’, a compound verb based on vestīgāre ‘track, trace’. This in turn was a derivative of vestīgium ‘footprint’, hence ‘track, trace’ (source of English vestige).
=> vestige

investigate (v.)

c. 1500, back-formation from investigation, or else from Latin investigatus, past participle of investigare "to trace out, search after" (see investigation). Related: Investigated; investigating.
