Semantic as one of the branches of pure linguistics is simply defined as the study of meaning in language. before going any further, first thing that you have to know is the word meaning itself, which becomes the focus of this study. Ferdinand de Saussure, one of the structuralism scholars introduces seven dichotomies in the effort to understand language, one of them is signifiant and signifie dichotomy. The first term refers to the form of language which is involved in a collection of phonemes, or in other words signifiant is the acoustic form of language or the basic form of phonological system of a language. Meanwhile, the second term refers to the mental image of a language, mental image refers to the intended meaning of it. De Saussure tried to tell us that in a language there must be symbols and thing that it's symbolized. The symbol can be so vary, it can be written, oral, and image, and the things represented by those symbols are generally called meaning.
