Martin (1992: 283):
This brings us to the point where two lexical items have been uniquely classified (define and read) and a step or two in delicacy would isolate several others (e.g. call, name, mean, denote, connote, spell, write, transcribe).
 In Fig. 5.5. (ibid.), the unique classification of define is given as:
- realise: stratum specific: semantics/grammar : wording: encoding
As demonstrated in the previous post, when the verb define serves as an identifying process, the direction of coding, like all identifying processes, can be encoding or decoding, depending on whether the Token or Value is the Identifier. The feature [encoding], therefore, does not classify the word define.
 Likewise, the unique classification of read is given as:
- realise: stratum specific: grammar/phon-graphology: encoding
As demonstrated in the previous post, the verb read did not serve as an identifying process in the clause provided. Rather, it served as a verbal process in a projection nexus. Accordingly, not one of the features specifying read — [realise: stratum specific: grammar/phon-graphology: encoding] — actually classifies the lexical item.
