Belly
Stomach, Abdomen
noun
The kanji and the word are exactly the same. That means they share meanings as well.
The reading is an exception, but it isn't too hard to remember. It's the same as 中 (なか), so if you think about it it makes sense. It's your insides, just like your belly is your insides!
