David Rose Confusing Determination With Reference

David Rose replied to Kieran McGillicuddy on Sysfling on 18/9/23 at 22:08:

You could start solving this problem by distinguishing lexicogrammatical from discourse semantic functions. The term Deictic denotes a function in a function structure at group rank... +Thing;+Deictic. It is realised at word rank by various classes of items.

Halliday starts his definition of Deictic functions of ‘the’ below on LG criteria, as specific, determinative

But then he switches to DS criteria to distinguish its function more delicately, from the functions of demonstrative and possessive determiners (as discussed with Bea on sysfling 9-10 September).

It’s not wrong, but doesn't make the switch explicit. In fact these delicate distinctions couple features from DS identification and LG deixis systems. Here’s parts of both...

[2] To be clear, as demonstrated here, Martin's (1992) discourse semantic system of identification is a rebranding of Halliday & Hasan's (1976) lexicogrammatical system of reference, which, among other things, confuses cohesive reference with nominal group determination. Rose here repeats that confusion in juxtaposing a reference system with a nominal group determination system as if reference and nominal group determination were the same function.
