To Be Raised, To Be Brought Up, To Grow Up
intransitive verb, godan verb
This word consists of kanji with hiragana attached. Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means raise so the verb vocab version means to be raised. P.S. This word is for when you are being raised, not when you are doing the raising of someone. That's 育てる. You'll learn it later.
そだつ
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you: When you were raised, you were raised completely on soda (そだ). That's all you drank. No water, no juice... just tons and tons of soda. Imagine this.
わたしは東京で生まれ育ちました。
I was born and raised in Tokyo.
このサボテン、元気に育ってるね。
This cactus is growing well.
いつの間にかその犬とコウイチの間には愛が育ちました。
Love grew between the dog and Koichi.
