Rooftop
Housetop
noun
Above the roof is the rooftop. What else would be up there?
おくじょう
This is a jukugo word that uses the on'yomi readings of the kanji. You didn't learn this reading for 屋 though, so here's a mnemonic to help you:
One place in the world has more rooftops than any where else, and that's Oklahoma (おく). They get so many tornadoes that they need extra rooftops for when the first few blow off.
今日、屋上でバーベキューをします。
We're doing a rooftop barbecue today.
夜きん明けにもかかわらず、屋上できんトレをしました。
I worked out on the rooftop in the morning even though I work the night shift.
屋上に上がって、天からふり注ぐ星の光を一緒にあびないかい?
Why don't we go up to the housetop and catch the star light shining down from the heavens?
