Etymology : Vestige is derived via Middle French from the Latin noun vestigium, meaning “footstep, footprint, or track.” Like trace and track, vestige can refer to a perceptible sign made by something that has now passed. Of the three words, vestige is the most likely to apply to a tangible reminder, such as a fragment or remnant of what is past and gone. Trace, on the other hand, may suggest any line, mark, or discernible effect (“the snowfield is pockmarked with the traces of caribou”). Track implies a continuous line that can be followed (“the fossilized tracks of dinosaurs”).
