The primary purpose of this paper is to establish the system of honorifics on the modern korean. There are many methods of polite expression in korean. It has been established as the polite expression of three methods by this time. Those are the subject honorific, object honorific and hearer honorific in modern korean. But we propose the speaker honorific above and beyond three methods in this paper. Because there are two elements to polite the speaker in common with other three methods in modern korean. An element is the lexical components and another element is the grammatical components. There are a personal pronoun 'ce' and many nouns as the lexical components and prefinal-ending 'sap', 'sao', 'cap', 'cao', 'op' as the grammatical component. The honorifics of modern korean are divided into the other people's honorifics and self honorific in this paper. The former are subject honorific, object honorific and hearer honorific and the latter is speaker honorific. The other people's honorifics are confronted with the feature of [+honorific] and [ honorific] respectively. The self honorific is confronted with the feature of [ politeness] and [-politeness].
