ABSTRACT
Descriptive model for linguistic analysis based on the ideas of J.R.Firth and formulated by M.A.K.Halliday. It proceeds from the notion that linguistic descriptions are abstractions of linguistic forms from linguistic utterances. Between language and the extralinguistic world there exists a close relationship which is produced by the situational context. Therefore, a system of mutually defining and deriving formal units guarantees an adequate and complete linguistic analysis.
