Monster to linger, annoyingly (4,2)
I believe the answer is:
drag on
I'm afraid I can't explain this answer.
Can you help me to learn more?
(Other definitions for drag on that I've seen before include "Continue interminably" , "Proceed for an extended period of time" .)
I've seen this clue in the Sydney Morning Herald.
Want a hint initially instead of a full solution?
