  • 泥沼どろぬまCommon

  • 沼沢しょうたくCommon
    nounA general term for marshy country, its characters meaning 'marsh' and 'swamp'; it covers bogs as one variety of such wet ground and is useful for speaking of the terrain in general.
  • 沼ぬまJLPT N1approx.Common
    nounA marsh or swamp thought of as a body of shallow, still water rather than simply wet ground; use it when 'bog' names a swampy pool or piece of marshland you could point to.
