Mountain Stream, Swamp
noun
The kanji and the word share the meaning of swamp, but this word is primarily used to mean mountain stream. Think of it this way, the water for a swamp has to come from somewhere right? It starts out up in the mountains and drains out into a swamp in the valley. The life cycle of a mountain stream into a swamp!
さわ
Since this word is made up of a single kanji, it probably uses the kun'yomi reading. You did not learn this reading, so here's a mnemonic to help you to remember: The beginning of the word swamp is actually pretty similar to this word's reading. さわ = "swa"? I'd say it's close enough to make a mnemonic out of in your head.
とても美しい沢ですね。
Isn’t this a really beautiful mountain stream?
この沢には沢ガニなど、たくさんの生き物が住んでいます。
Many creatures such as freshwater crabs live in this stream.
沢の音を聞きながら歩くのが好きなんです。
