Waiting Room
Meeting Place
noun, verbal noun
The place you wait to join other people is a waiting room or a meeting place.
The readings for this word are both kun'yomi readings, but it's like the hiragana that normally sticks out is stuffed in. 待ち → 待, 合い → 合 and is pronounced the same too. I know it's confusing, but once you get it down you'll never forget!
