West
noun
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 should use the kun'yomi reading. You learned that reading with the kanji, but here's a mnemonic refresher just in case:
You go off to the west. It's the Wild West, even. There aren't many people out here, making it easy to find a niche (にし) for your snake oil business.
西はどっちの方ですか？

西日本の生まれです。

会社の西にはコンビニやスーパーがたくさんあります。
There are many convenience stores and supermarkets west of the company.
