South
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, so you might remember it, but here's a mnemonic refresher just in case:
Think about the south. What's down there? Mean Amy (みなみ) lives down there. Think of the last mean thing she did to you and imagine it while yelling out "MEAN AMYYYYY" at the sky.
南に山がある。
There is a mountain in the south.
入り口は南の方にあります。
The entrance is in the south.
南の国に行きたいなぁ。
I want to go to a southern country.
