Transitive verb and Godan verb
はく
会議が始まる前に、会議室をちょっと掃いておいてもらっていいかな。
Could you sweep the meeting room before the meeting starts?
Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means sweep so the verb version is to sweep.
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: While you sweep you laugh. "HA (は) HA HA!" Just imagine yourself doing this, or do it for real if you want to clean up a bit.
