The old graph is called original character, and the new generated one is called derived character. Two kinds of phenomena-derivation of cognate words （同詞孳乳） and differentiation of unidentical words （異詞別異）-promote the derivation of Chinese characters. In return, derived characters not only bear meaning of the original one, but also serve as a symbol of an independent word and consolidate the graph-meaning relationship. It deserves much attention to the law of the process of character derivation.展开更多
