Abstract: Cheng Yaotian, a scholar in the Qing Dynasty, wrote an article named Guo Luo Derivation, in which he links up 332 cognates starting from the word "Guo Luo" and expounds the sound transformation principle and the rule of naming things, i.e., "the sound follows the shape and the character follows the sound". On the basis of Wang Yin's modern Chinese translation and contemporary academic interpretation of Guo Luo Derivation, three features of Cheng Yaotian's embodied cognition on cognates can be found from the perspective of Embodied-cognitive Linguistics (ECL): the co-occurrence of elegance and ordinariness instead of their binary opposition, the dynamic embodiment of word derivation instead of static classification of word categories, the integration of word and iconicity beyond the current theories of motivation. Based on the three features and by studying the Embodied-cognitive Mechanism, the Embodied-cognitive Logic of cognates is constructed, which verifies the fundamental function of "reality" in ECL and also shows the importance of "language" itself in word formation and the Embodiment - cognition of Language.
