Abstract: The theory of linguistic adaptation initiated by Jef Verschueren claims that lan guage production and language understanding result from mutual effect among such pragmatic factors as variability, negotiability and adaptability. This paper at tempts to apply such a pragmatic theory to re-examining translation pr ocess and translation nature. The author holds that translation in essence is th e process based on variability, negotiability, adaptability and choice, and that translation process from the perspective of the theory of linguistic adaptation is a dynamic interpretation process in view of the three language features, whi ch mutually coordinate and jointly continue utterance production, understanding and transformation.
