Elaborating Hypotactic Verbal Group Complexes: Time-Phase Causative

Halliday & Matthiessen (2004: 511-2):

(1) durative: the ball kept rolling

causative: John kept the ball rolling

(2) inceptive: the ball started/stopped rolling

causative: John started/stopped the ball rolling …

Note that these then have passives: the ball was kept/started/stopped (from) rolling (by John).
