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 hit so the vocab is to hit something or to strike something. It can also mean to type.

You can use this word to describe bumping a part of your body on something, hitting a ball or a nail, or typing on a keyboard. It can also describe hitting a person, but that use is less common and sounds a bit literary.

This word uses the kun'yomi reading, which you haven't learned yet, but never fear! A mnemonic is here:

If you’re planning to hit an uni (う), you’re going to need a special bat or hammer. I don’t know why you’d want to hit a sea urchin, but make sure you have the right equipment if you do, because those things are spiky!
