Empty

Mnemonic

Giving a roof legs is the kind of construction you do. You make it so a roof can be in the sky. In addition to meaning "sky", this kanji often means empty. Think about it - there's nothing more empty than the sky!

Hints

Think about it. If you give a roof legs, it goes even higher up. What's higher up? The sky is!

Mnemonic

The reason you want to put a roof in the sky is because it gets the roof away from all the cooties (くう) that are on the ground.

Hints

Say "coooooties" nice and long, just like a little kid, to emphasize the long vowel in くう.
