Origin & History of “ground”

Ground is part of a widespread family of Germanic words, which include also German, Swedish, and Danish grund and Dutch grond. A common meaning element of all these is ‘bottom’, particularly of the sea (preserved in English ‘run aground’), and it seems that their prehistoric Germanic ancestor *grunduz may originally have denoted something like ‘deep place’.
