Fence
noun
The kanji and the word are exactly the same. That means they share meanings as well. Isn't that fencetastic?
さく
This word uses the on'yomi, which you learned with the kanji. Just think about the sack (さく) hanging on the fence.
柵に足がはさまって抜けない。
My leg got stuck in the fence and I can't get it out.
今日の午後は柵をペンキでぬります。
I'll paint the fence this afternoon.
その犬は柵を軽々と跳び越えてしまった。
That dog jumped over the fence so easily.
