Halliday & Matthiessen (1999: 225, 226):
Thus our concept of "construing experience through meaning" refers to the construal in human consciousness of an ideational system in which such motifs play a critical part. Expansion and projection are, as we put it earlier, fractal principles; they generate organisation within many environments in the ideation base, at different strata and at different ranks within one stratum. These environments are thus related to one another through the local manifestations of these different motifs; and this opens up the system's potential for alternative construals of experience: for example, the types of expansion create new meaning potential through "figures of speech" (see Figure 5-15).
