It is part of a social semiotic approach to language called systemic functional linguistics. In these two terms, systemic refers to the view of language as ``a network of systems, or interrelated sets of options for making meaning''; functional refers to Halliday's view that language is as it is because of what it has evolved to do (see Metafunction). Thus, what he refers to as the multidimensional architecture of language ``reflects the multidimensional nature of human experience and interpersonal relations.''

Its function includes the control of posture, and the coordination of movements of parts of the body, including the eyes and head as well as the limbs. Further it is involved in motion that has been learned and perfected though practice, and will adapt to new learned movements. Despite its previous classification as a motor structure, the cerebellum also displays connections to areas of the cerebral cortex involved in language as well as cognitive functions. These connections have been shown by the use of medical imaging techniques such as fMRI and PET.
