I’m learning Japanese through self-study.
Why don't you learn how to make weird faces and poses with Tofugu, instead of studying Japanese?
Learning is important, but perhaps what’s more important is how you learn.
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 study or learning. When you do these things, what ends up happening? You learn. That's why this word means to learn.
There is another word that means "to learn" that is going to be more common, which is 習う. You'll learn this one later on. 学ぶ sounds a little more serious compared to 習う, so keep that in mind when you use it.
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 have to remember the まな part to learn this word's reading. Think about a class you're taking. It's a manners class, and you're there to learn manners (まな). Imagine this study of manners and imagine yourself practicing it.
