Extending Hypotactic Verbal Group Complexes: Potentiality Causative

Halliday & Matthiessen (2004: 512):
Here there are causative forms as follows:
(1) potential: the patient can see clearly
causative: this enables the patient to see clearly
(2) achieval: John learnt to fly
causative: Mary taught John to fly
Again, these causatives have passives: the patient is enabled to see clearly, John was taught to fly by Mary.
