For the textual and interpersonal analyses, see Halliday & Matthiessen (2004: 97, 157).
For the experiential analysis, the reasoning is as follows:
- for Token-Value structure, compare the agnate clause: John represents the one that I love where John functions as (the less abstract) Token (see Halliday & Matthiessen 2004: 231);
- for Identifier-Identified structure, consider the probe: Which represents the one that I love?; that is, the one that I love is identified by John, so John functions as the Identifier (see Halliday & Matthiessen 2004: 228). Also, in the unmarked case, the Identifier conflates with the New information, as it does here (Halliday & Matthiessen 2004: 229).
