To Visit
transitive verb, ichidan verb
Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means visit, so the verb vocab version is to visit.
訪ねる is a somewhat formal word you'll mostly encounter in writing or very polite speech. It implies visiting somewhere or someone with a clear purpose. You're not just dropping in because you were in the neighborhood — you have good reason to be visiting that specific place or person!
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:
You want to visit your friend Taz (たず), the Tasmanian Devil. He's your best bro, so imagine visiting him and having a good time and saying you're going to visit him again.
家を訪ねる前に、電話してみた方がいいよ。
You should call her before visiting.

Nobuko, don't open the door even when a stranger visits the house.
