Modality Is Grounded In The Initiating Rôle Of An Exchange

Halliday & Matthiessen (2014: 177):
Note that in a statement the modality is an expression of the speaker’s opinion: that will be John ‘that’s John, I think’; whereas in a question it is a request for the listener’s opinion: will that be John? ‘is that John d’you think?’. Modality is thus grounded in the initiating role of an exchange.
