Range In Emanating Mental Clauses: Phenomenon

Halliday & Matthiessen (2014: 347):

[In the like [‘emanating’] type of mental process] the Phenomenon bears no kind of resemblance to a Goal.  But it does show certain affinities with the Scope.  It figures as Subject, in the ‘receptive’, under similarly restricted conditions; and it appears in expressions, such as enjoy the pleasure, saw the sight, have an understanding of, which are analogous to material Scope expressions of the ‘process’ type, such as play a game, have a game.  So we can interpret the rôle of the Phenomenon in the like type of mental process as a counterpart of that of Scope in the material; it is the element which delimits the boundaries of the sensing.
