Net, Netting, Web
noun
The kanji and the word are exactly the same. That means they share meanings as well.
あみ
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: When it comes to nets, you gotta go talk to Amy (あみ) if you want a good one. Only Amy makes good nets.
うちの娘が虫取り網が欲しいと鼻を鳴らしてせがむもんだから、ついつい買ってあげたんだよ。
My daughter sucked up to me to get the butterfly net she wanted and I ended up buying one for her.
