The Ergative Model: Causation Of The Process [Defining Variable]

Halliday & Matthiessen (2004: 286-8):
… while … there is clear evidence in the grammar for distinguishing one process type from another, there is also clear evidence for saying that, in a more abstract sense, every process is structured in the same way, on the basis of just one variable. This variable relates to the source of the process: what it is that brought it about. The question at issue is: is the process brought about from within, or from outside? … the variable is not one of extension but one of causation. Some participant is engaged in a process; is the process brought about by that participant, or by some other entity?

The Transitive Model: Extension Of The Process [Defining Variable]

Halliday & Matthiessen (2004: 287):
… the variable is one of extension. … does the process extend beyond the Actor, to some other entity, or not?

The Transitive Model

Halliday & Matthiessen (2004: 282):
the transitive model is based on the configuration of Actor + Process. The Actor is construed as bringing about the unfolding of the Process through time; and this unfolding is either confined in its outcome to the Actor or extended to another participant, the Goal. The Goal is construed as being impacted by the Actor’s performance of the Process.
