Circumstantiation: taking a broader look at circumstantial meanings

This paper argues for a view of circumstantial meaning as a region of ideational meaning that is instantiated across a range of lexicogrammatical structures: from the rank of the clausal constituent of circumstance in both directions: up to clause rank and down to below or within constituent rank (eg as Qualifier). This paper brings together and extends the work of Halliday & Matthiessen (An Introduction to Functional Grammar, 2004) on expansion and circumstantiation, and the work of Martin (English Text: System and Structure, 1992) within the discourse semantic system of ideation. Each type of circumstantial meaning is defined structurally, that is, according to rank, and semantically, according to type. Analysis of circumstantial meanings is conducted on a small corpus of four introductions to journal articles in order to demonstrate the use of viewing circumstantial meaning in this way.
