Contextualism is an adaptabilitybased generative view in the framework of Linguistic Adaptation Theory and holds that contexts are not given but are the constrained generating procedures. The generative view of context raises into a new theoretical level for our understanding of the relationships between constructability, self organization, constraining property and emergent property, which includes three distinctive features: (1) “generation” is “constrained”; (2) “procedures” are paid more attention to than “results”; (3) “generation” is “emergent”. 
