Silk
noun
The kanji and the word are exactly the same. That means they share meanings as well.
きぬ
Since this word is made up of a single kanji, it probably uses the kun'yomi reading. You already learned this reading with the kanji, but here's a mnemonic in case you need to refresh your memory: Wearing silk is the key (き) to not being nude (ぬ). Wear it!
母の日に、絹のハンカチをプレゼントしました。
I gave a silk handkerchief as a gift on Mother's Day.
これはおばあちゃんが大切にしていた絹の着物です。
This is a silk kimono that my grandmother cherished.
え、シルクって絹のことなの？
Wait, is silk the same as kinu?
妻は、美しい絹のガウンを羽織って死んでいました。
My wife was found dead wearing a beautiful silk gown.
