Though English is categorized as a Germanic language, there’s no denying the enormousness of Latin’s footprint on its lexicon. Among English’s plethora of Latin derivatives is vestige, a word that traces back to the Latin noun vestigium, meaning "footstep, footprint, or track." Like its forebear, vestige refers to a perceptible sign made by something that has passed, or to a tangible reminder, such as a fragment or remnant, of what is past and gone. Vestige also happens to be one of only a few vestiges of vestigium itself, along with the adjective vestigial ("remaining as the last part of something that existed before") and the familiar verb investigate.
