Knoll
Noun
おか
初めてマニュアルで運転した時、丘のてっぺんでエンストしてしまいました。
On my first day of driving a stick, my car stalled at the top of a hill.
The kanji and the word are exactly the same. That means they share meanings as well.
The reading for the vocab version of this word is the same as 岡 which has the same meaning and the same reading. Lucky!
