This well-illustrated book outlines a framework for the analysis of syntactic structure from a perspective of a systematic functional grammar. In oart, the book goes back to the grammar's "scale and category" roots, but now with the aim of presenting how a descriptive framework illustrating how the analysis of the syntactic structure can reflect the meaning structure.The contents are divided into four sections. Section one gives a brief overview of systematic grammar, including the linguistic system, context of situation, and language fractions. Developing the lexicogrammar, section two considers formal units and their classes, but the principal focus is on section three, which covers the role of units as elements of structure. Section four discusses areas of structural complexity and concludes with several refinements to the analysis format.
