Gets upset, too, when you rebuke (4,2)
I believe the answer is:
pull up
'rebuke' is the definition.
Although both the answer and definition are verbs in their base form, I can't understand how one could define the other.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for pull up that I've seen before include "Take to task" , "Stop or cause to stop" , "Exercise" , "Halt" , "park" .)
