為數不少的甲骨非常殘碎，內容也相對不完整。研究甲骨時若能將有關主題的殘龜斷骨加以綴合，是研究的基礎。甲骨綴合有時被視為一種隱微的知識，好像是各自摸索出各自的方法。以往有不少文章涉及甲骨綴合及方法，或提出綴合原則，或論及綴合所依恃的條件，或專門討論綴合方法，這些內容對於甲骨綴合工作的延續及進展功不可沒。為使初學者容易掌握，甲骨綴合的方法或經驗最好是談得愈細節愈好，而且這些細節本身就是甲骨學知識的一部分。以往對綴合方法的討論，多著重在大範圍、原則性的論述。因此本文根據作者的經驗及積累的甲骨學相關知識，分別從不同內容的甲骨殘片，呈現在這些例子中作者如何「推知殘辭」，進而「限縮查找綴合版的範圍」的綴合方法。

Oracle bones are often in fragments and so are the inscriptions on them. Rejoining the fragments of the similar themes is one of the significant research works in oracle bone studies. Oracle bone rejoining is often seen as an obscure knowledge and not many clear instructions are there for the researchers to come.Numerous research papers in the literature have offered princples, methods, or qualifications of oracle bone rejoining, but they tend to cover only the general idea. To make it easier for the beginners, I argue that if the more details of the instructions can be shared,the better understandng of the methods can be achieved. Thus I will share my years of experiences in the field so as to show how to infer the missing words from the rejoinings and to narrow down the search range for the missing parts.
