White Flag
noun
A white flag is a white flag. It's one for surrender. I give up! Too many kanji!
You'll have to be careful about this one, as it's actually read with the two kanji's kun'yomi readings put together, making this しろはた.
白旗を上げるということは、敵に降伏するということだ。
Raising a white flag means surrendering to the enemy.
