Misunderstanding Lexis As Most Delicate Grammar

Martin (2013: 97):

This is misleading. To be clear, each lexical item is the synthetic realisation of a set of the most delicate grammatical features, as in Hasan's approach, not the realisation of a single grammatical feature, as in Martin's approach. Halliday & Matthiessen (1999: 198-9):

Note that it is not (usually) the lexical items themselves that figure as terms of the systems in the network. Rather, the systems are systems of features, and the lexical items come in as the synthetic realisation of particular feature combinations.

An analogy can be found in phonology. For example, the phoneme /b/ is the synthetic realisation of the set of features [voiced, bilabial stop], not the realisation of a single articulatory feature.
