Halliday & Matthiessen (2014: 29n):
Here the term ‘register’ thus refers to a functional variety of language (see e.g. Halliday, 1978; Hasan, 1973; Matthiessen, 1993b; Ghadessy, 1993; Lukin et al., 2008). It has also been used in a related, but different way, to refer to the contextual values associated with such a functional variety (see Martin, 1992, and other contributions to the ‘genre model’ within systemic functional linguistics; cf. Matthiessen, 1993b).
Blogger Comment:
Here Halliday's reviser, Matthiessen, fails to warn the reader that:
A. Martin's use of 'register' is:
- inconsistent with the notion of register,
- inconsistent with the notion of context, and
- inconsistent with Systemic Functional Linguistic theory;
B. Martin's use of 'genre' is:
- inconsistent with the notion of genre,
- inconsistent with the notion of context,
- inconsistent with Systemic Functional Linguistic theory, and
- not equivalent to Martin's use of 'register'.
Evidence here.
