Followers regret painful remark and make minor improvements (7)
I believe the answer is:
retouch
'followers regret' is the definition.
Although both the answer and definition are verbs in their base form, I cannot understand how one could define the other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for retouch that I've seen before include "Paint over" , "Make slight improvements to (a photo/picture)" , "Improve a photo, with a pencil say" , "Repair a painting" , "Fine-tune" .)
