Medium/Process: Meteorological Processes

Halliday & Matthiessen (2004: 289):
For the sake of simplicity, we represent meteorological processes such as it’s raining as having no Medium; but it would be more accurate to say that here the Medium is conflated with the process.

The Medium [Distinguishing Characteristics]

Halliday & Matthiessen (2004: 289):
Except in the special case of the medio–receptive voice, the Medium is obligatory in all processes; and it is the only element that is, other than the process itself. … The Medium is also the only element that is never introduced into the clause by means of a preposition (again with the same exception of medio–receptives); it is treated as something that always participates directly in the process.

The Medium [Definition]


Halliday & Matthiessen (2004: 288-9):
Every process has associated with it one participant that is the key figure in that process; this is the one through which the process is actualised, and without which there would be no process at all.  Let us call this element the Medium, since it is the entity through the medium of which the process comes into existence. … in a material process the Medium is equivalent to the Actor in an intransitive clause and Goal in a transitive clause.

Medium

Halliday & Matthiessen (2004: 284):
… the medium through which the process is actualised.

The Clause Nucleus

Halliday & Matthiessen (2004: 289):
The Process and the Medium together form the nucleus of an English clause; and this nucleus then determines the range of options that are available to the rest of the clause. Thus the nucleus … represents a small semantic field which may be realised as a clause either alone or in combination with other participant or circumstantial functions.
