Misrepresenting Halliday (1993) On The Realisation Statement 'Expand'

Fawcett (2010: 184):

The last realisation operation that requires a comment is Halliday's Operation (e) of "Split". This has no equivalent in the Cardiff Grammar. A "Split" operation is only needed in a grammar which represents both 'primary' and 'secondary' structures (as introduced in "Categories" and still used regularly for some aspects of structure in IFG). Halliday introduces it to enable the grammar first to generate what he would term a 'primary structure' (such as "Mood + Residue" in Figure 7 in Chapter 7), and then to 'split' the 'Mood' element into the two elements of its supposedly 'secondary' structure, i.e., into "Subject + Finite". Halliday does not explain why he thinks it desirable to generate the "Mood" element first and then to split it into two, but we can presume that the intention is to give expression to the idea that the "Mood + Residue" structure is 'primary' and the "Subject + Finite" structure is 'secondary'. Nor does Halliday explain what would actually happen in practice when a "Split" operation is carried out.

The reason why the Cardiff Grammar has no such realisation operation is, of course, that we recognise only one degree of 'delicacy' in the structures of the clause, so that there is no need for an operation whose function is to add another line of analysis to the representation. Instead, we treat the Subject and the Operator (Halliday's "Finite") as direct elements of the clause.

[1] Trivially, Halliday (1995 [1993]: 272) does not propose an Operation of "Split", but a realisation statement of 'expand':

(e) 'Expand' an element into a further configuration (e.g., expand mood into subject+ finite);

[2] Non-trivially, the grammar does not first "generate" a Mood element and then expand it into Subject and Finite elements. This is to mistake a system network of relations for an algorithmic procedure. The identity relation between system and structure is intensive (elaboration), not circumstantial (enhancement: temporal).

[3] This is misleading. It is only Fawcett who regards these structures as 'primary' and 'secondary'.

[4] This is misleading. On the one hand, Halliday does explain why a Mood element is necessary. For example, the presence of the Mood element realises the feature 'indicative' (Halliday 1994: 74). On the other hand, the realisation statement 'expand' is not used in the system network of MOOD; Halliday & Matthiessen (2014: 162):

[5] To be clear, Halliday's explains that this realisation statement expands an element into a further configuration. 

[6] To be clear, in SFL Theory, delicacy (hyponymy) is a sub-type of elaboration (Halliday & Matthiessen 1999: 145) and a dimension of systems, not structures. In contrast, the relation of Subject and Finite to the Mood element is composition (meronymy), a subtype of extension (Halliday & Matthiessen 1999: 146).

[7] This is misleading, since Subject and Finite are "direct" elements of the clause in SFL Theory also. Or more precisely, the notion of 'direct' is irrelevant here, deriving, as it does, from Fawcett's misunderstanding of a system network as a sequenced algorithm; see [2] above.
