To Separate Something
To Divide Something, To Share, To Classify
transitive verb, ichidan verb
This word consists of kanji with hiragana attached. Because the hiragana ends with an う (in this case る) sound, you know this word is a verb. The kanji itself means part. When you're parting something, you're essentially separating something from others. So, this means to separate something or to divide something. Depending on the context, it can also mean to share or to classify.
Be careful not to confuse it with 分かる, a similar word with a different meaning. To do so, you'll need to learn the reading. Think of it this way: You "separate" what you care (ける) about from everything else. You want to separate those special things you care about from all the other things you don't care about.
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:
