In this paper I have studied that the semantic aspect of the so-called presupposition is so complex that they can not be explained in a uniform phenomenon. Therefore, presupposition must be divided into the semantic and pragmatic aspect and explained with such two aspects. Also, we have known that the notion of semantic entailment rather than semantic presupposition is adequate in the explanation to the presupposition. Meanwhile, in the pragmatic aspect, presupposition depends upon the discourse contexts and must be explained with the notion of implication. According to Karttunen and Peter this notion is equivalent for the conversational implicature.
And in the complex sentenses, the entire presupposition is influenced by the semantic feature of the sentences. then we have seen that felicity condition and conversational maxims are required to the explanation of the complex sentences.
Finally, implication can be divided into the conversational and conventional one. Then presupposition must be decomposed into entailment implicature. Here, conventional implicature is absorbed in the notion of entailment and implicature is just word for the conversational one.
As a result, so-called presupposition must be decomposed into two parts which can be explained in the semantics and pragmetics. Then the semantic aspect including the conventional implicature which can be solved by truth condition must be explained by entailment. And conversational implicature must be explained by pragmatics.
