Soup, Juice
noun
The kanji and the word are exactly the same. That means they share meanings as well.
しる
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: You are given some soup. You take a bite and your mouth is cut clean off. That is because you're eating sheer (しる) soup.
熱々の豚汁をもらえますか。
Can I have the boiled pork miso soup, please?
