To Dance
intransitive verb, godan verb
Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means dance and the verb vocab version means to dance.
The reading is the same as the one you learned with the kanji.
海の中の魚達は、みんな太鼓の音に合わせて一斉に踊り出しました。
All the fish in the sea started dancing to the sound of the drum.
