Problems With The System Of External Comparison

Martin & Rose (2007: 125):
In sum, options for external comparison include similarity or difference: opposite, replacing or excepting, set out in Figure 4.2.

Blogger Comments:

To be clear, the authors' system of comparison misconstrues 3 subtypes of extension as 3 subtypes of comparison (enhancement) and rebrands these grammatical features as discourse semantic. Specifically:
  1. adversative addition is misconstrued as comparison and rebranded as different: opposite;
  2. replacive variation is misconstrued as comparison and rebranded as different: replacing;
  3. subtractive variation is misconstrued as comparison and rebranded as different: excepting.

Cf. Halliday & Matthiessen (2014: 471):

Again, the serious theoretical disadvantage of misunderstanding these expansion relations and rebranding them as discourse semantics is that it creates an incongruent relation between grammar and discourse semantics even in the absence of grammatical metaphor.
