Object to name having to be changed around (6)
I believe the answer is:
resent
'object to' is the definition.
(to resent something is to dislike it)
'name having to be changed around' is the wordplay.
I cannot quite understand how this works, but
'name' could be 'n' (common abbreviation e.g. on forms) and 'n' is present in the answer.
'around' could be 're' (regarding) and 're' is present in the answer.
The remaining letters 'set' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for resent that I've seen before include "Feel bitter or indignant about" , "Feel indignation at" , "Take something as an affront" , "Don't like" , "Dispatched again - take amiss" .)
