Undiminished in sensitivity for others (6)
I believe the answer is:
intact
'undiminished' is the definition.
(I've seen this before)
'sensitivity for others' is the wordplay.
'sensitivity' becomes 'tact' (I've seen this before).
'for' says to put letters next to each other (I've seen this in other clues).
'others' becomes 'in' (I can't justify this - if you can you should believe this answer much more).
'tact' after 'in' is 'INTACT'.
'in' is the link.
Can you help me to learn more?
(Other definitions for intact that I've seen before include "Not damaged or missing a part" , "All in one piece" , "Undiminished" , "Complete - unbroken" , "Undamaged, not broken" .)
