Abstract

Semantic implicatures are features for understanding the use of sentences. The status of this implementations of meaning is a quasi-logical relation as a "weak implication". They are determinated through types of lexical units and expressions in grammatical positions. But both are only necessary conditions for semantic implicatures. Further assumption for meaningful use of sentences are presupposed e.g. existence presuppositions, evidences, customs etc. So, the delimination to pragmatic (presuppositions) is indicated.
