Abstract: In dealing with the identification of loaned antithesis in ancient poems, the present paper, taking into consideration of language and literature, and starting from the general principle of language communication, comes to the following 4 points: 1. In forming a perfect antithesis by adopting the sense of a homophone in the sentence, one of the premises was that the loaned sense was not to be in conflict with the true sense and context of the original couplet; if it occurred in the structure of a certain term or expression, it should be able to be combined at least with the term or expression in sense. 2. Loaned antithesis did not happen to emphatic words and terms and the frequently-used set structures. 3. Neither did it happen to the naturally matchable things, senses, artistic conceptions, etc. which people at that time were willing to accept. 4. Since its aim was to achieve the perfection of antithesis, the true loaned ones could be verified by reversed inference.

Key words: antithesis, loaned antithesis, perfect antithesis, context, emphatic words and terms, reversed inference
