The kanji 契 is a pictographic character. It is composed of two parts: the top component is 大 meaning "big" or "person," and the bottom is 刀 meaning "knife" or "cut." The original meaning of the character was related to cutting or carving into wood. This evolved to represent a physical agreement. Later it was used to symbolize the act of carving a pledge or agreement, such as on a wooden tablet. This physical act then represented a more abstract concept of commitment and the binding nature of an agreement.
