1. External Temporal Conjunction
Halliday & Hasan (1976: 239, 240):
… it is a relation between events […] first one thing happens then another. The time sequence […] is […] in the content of what is being said.
… the cohesion has to be interpreted in terms of the experiential function of language; it is a relation between meanings in the sense of representations of ‘contents’, (our experience of) external reality.
… those which exist as relations between external phenomena …
2. Internal Temporal Conjunction
Halliday & Hasan (1976: 239, 240):
The time sequence is in the speaker’s organisation of his discourse. … a relationship between different stages in the unfolding of the speaker’s communication role — the meanings he allots to himself as a participant in the total situation.
… the cohesion has to be interpreted in terms of the interpersonal function of language; it is a relation between meanings in the sense of representations of the speaker’s own ‘stamp’ on the situation — his choice of speech role and rhetorical channel, his attitudes, his judgements and the like.
… those which are as it were internal to the communication situation.
