Expansion And Projection

Halliday & Matthiessen (2004: 367):
Circumstances augment the configuration of process + participants in the clause in terms of either projection or expansion. These two types of relation correspond, in turn, to different process types: projection corresponds to verbal and mental clauses, and expansion corresponds to relational clauses. Projection and expansion are also manifested as the logico-semantic relations that link clauses together to form clause complexes.
