“Well, I helped decorate, but John was the brains behind the operation.”

Sometimes it takes many people to do something (something good like a birthday party, or something bad like a major crime). Often there is one person who had the idea and thought of how to make it work. We say they are “the brains behind it”.


誕生会など良いこと、大きな犯罪など悪いこと、たくさんの人が協力しないとできないことがあります。誰かが言い出して、どんな風にすればできるかを考えます。こういった時にその人が「the brains behind it」と言います。
