Sense and reference constitute the personal images of any given words.Three sources of meaning are elaborated: the dictionary sense, the personal images of any given words, and the dynamic context.A combination of traditional semantic meaning and dynamic pragmatic meaning analysis is suggested through examining the meaning derivation process in the cases of the use of referring expressions in definite, indefinite descriptions, and incomplete sentences.展开更多
