The kanji and the word are exactly the same. That means they share meanings as well.
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: Please hand me the rope, right now (なわ), otherwise I will fall to my death!
Both ropes look the same to me. I can’t tell the difference at all.
