To Teach, To Tell
transitive verb, ichidan 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 teach so the verb vocab version means to teach. It's also used to mean to tell in a more general sense.
おしえる
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: Think about your favorite teacher. Now think about them teaching you the following: "Today I'm going to teach you about the ocean (おし)." It is big. Really big. Inside it are krakens, space aliens, and lost cities. Here is where you continue the lesson in your head, making it the most ridiculous lesson about the ocean you've ever heard. Focus in on the ocean part, since that's the reading, always coming back to it.
