〔R51〕  Alone, no life can be without me;

                With C, I hold the wildest beast;

                With G, I measure land and sea;

                With P, I serve the nobleman;

                With R, I rave with passion dread;

                With S, I know the depths of wisdom;

                With W, I earn my daily bread.

〔譯註〕 單獨時，沒有生命能夠沒有我。

有了C，我就抓住最野的野獸；

有了G，我能測量陸地和海洋；

有了P，我便服侍高貴的人樣；

有了R，我便狂叫情緒很恐怖；

有了S，我會知道智慧的深度；

有了W，我就賺取麵包來過日。

〔提問〕 If I am a three-letter word, what is the word?
