Halliday & Matthiessen (1999: 262):
We have shown that the typical manifestation of grammatical metaphor in discourse is as a 'syndrome' of features including both class shift and rank shift. Let us now recall two of the frequently occurring syndromes described earlier, noting where these features occur:(1) Their frequent dismissal of personnel does not inspire people's confidence
[class shift]: process 'dismiss' as thing, relator 'cause' as process ['inspire'], quality 'confident' as thing
[rankshift]: sequence as figure[congruent variant]: Because they frequently dismiss personnel, people are not confident [in them](2) Rapid bonding resulted
[class shift]: process 'bond' as thing, relator 'cause' as process
[rankshift]: none (figure as figure)[congruent variant]: As a result [the substances] rapidly bonded.Note that in (2) the other term in the relation is to be presumed from the preceding text.
