Realisation Relates Levels Of Abstraction

Halliday & Matthiessen (1999: 4, 385):
Language, therefore, is a resource organised into three strata differentiated according to order of abstraction. These strata are related by means of realisation. …The strata are ordered in symbolic abstraction

Halliday & Matthiessen (1999: 25):
Every scientific theory is itself a stratal-semiotic system, in which the relation among the different levels of abstraction is one of realisation.
