Cleaning
noun, する verb
Sweep and exclude all that dirt from the floor, please. When you do this a lot, it becomes cleaning.
そうじ
This is a jukugo word, which usually means on'yomi readings from the kanji. For this one though, you have to remember to read the 除 part as じ. Just keep in mind that cleaning (cleanliness) is next to godliness and so is Jesus (じ). So, Jesus is like cleaning. Easy.
まずやるべきことをやらなくてはね。部屋の掃除から始めようか。
First things first. Let’s start by cleaning your room.
