The Integrational theory of language[1] is the general theory of language that has been developed within the general linguistic approach of integrational linguistics.
Differently from most other approaches in linguistics, integrational linguistics emphasizes a distinction between theories of language and theories of language descriptions. Integrational linguistics has therefore developed both a general theory of language and a theory of linguistic descriptions, the integrational theory of grammars.[2][3]
The integrational theory of language contains two major subtheories: (i) the integrational theory of linguistic variability, which is 'conflated' with (ii) the integrational theory of language systems.
One of the most distinctive features of the integrational theory of language is its adherence to ontological explicitness and constructiveness: the ontological status of every linguistic entity postulated by the theory is clearly determined (explicitness), and every entity is a logical or set-theoretical construct ultimately related to a small number of sets of basic entities that include, in particular, objects and events in space-time (constructiveness).[4]
