Crab
noun
The meaning is the same as the kanji's meaning, crab. If you know this word, and you know the word 鰐 as well... then, well, you know something, though I'm not sure what that something is.
The reading is the same as the one you learned with the kanji. But you knew that already, didn't you?
お腹がすいてきた。晩ご飯の蟹が楽しみだ。
I’m getting hungry. I’m looking forward to having crab for dinner.
