JLPT N1

Meaning and Usage

"沼" (ぬま) primarily refers to a swamp, bog, or marshy pond. It describes wet, muddy land often covered with water and vegetation. This word is used in both literal geographical contexts and metaphorically.

Literal Use

In natural settings, "沼" denotes areas where water accumulates and the ground is soft and wet. It is common in descriptions of landscapes, ecology, or when giving safety advice about walking in such areas.

Metaphorical Use

"沼" is often used metaphorically to describe a situation or interest that one gets deeply involved in, sometimes to the point of being unable to escape easily. For example, "趣味の沼" (the swamp of a hobby) implies becoming absorbed or obsessed with a hobby.

Common Collocations

  • 沼地 (ぬまち): swampy land, marsh
  • 沼にハマる: to get stuck in a swamp / to become obsessed
  • 大きな沼: a large swamp

Register and Nuance

"沼" is a neutral noun used in both formal and informal contexts. When used metaphorically, it often appears in casual conversation or writing to express deep involvement or obsession.

Learner Tips

Be careful not to confuse "沼" with "池" (いけ), which means pond but usually refers to a cleaner, more contained body of water. "沼" implies muddier, wilder, and often less accessible water areas.
