Arm
noun
The kanji and the word are exactly the same. That means they share meanings as well.
The reading is the same as the one you learned with the kanji.
「フグのこと、どう思う？」「正直に言うと、私の好みじゃないわ。私はキンニクマみたいに筋肉モリモリの腕の男が好きなの。」
"What do you think of Fugu?" "To be honest, I don’t like him. I prefer a guy with muscular arms like Kinnikuma."
