Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means make money, so the verb vocab version is pretty similar: to make a profit.

儲ける means to gain something in a way that feels profitable or advantageous. It's most common in money talk, like 株で儲ける (make a profit from stocks), but it can also describe other kinds of lucky or beneficial gains. For example, you might 一日儲ける (gain an extra day) thanks to a lucky turn of events or an efficient way of doing something.

Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You learned this reading already with the kanji, so you're good to go! Woo-hoo!
