A quagmire covered with grass or other plants. It is defined by marsh, and morass, but differs from a marsh, as a part from the whole. Wet grounds are bogs, which are the softest and too soft to bear a man; marshes or fens, which are less soft, but very wet; and swamps, which are soft spongy land, upon the surface, but sustain man and beast, and are often mowed.

A little elevated spot or clump of earth, in marshes and swamps, filled with roots and grass.

To whelm or plunge, as in mud and mire.
