Exhausted following gender reassignment police officer initially belittled (10)
I believe the answer is:
diminished
'belittled' is the definition.
(I know that belittled can be written as diminished)
'exhausted following gender reassignment police officer initially' is the wordplay.
'exhausted following gender reassignment' becomes 'minished' (I can't justify this - if you can you should believe this answer much more).
'police officer' becomes 'di' (detective inspector).
'initially' is a charade indicator (letters next to each other) (some letters go before others).
'minished' after 'di' is 'DIMINISHED'.
Can you help me to learn more?
(Other definitions for diminished that I've seen before include "run down" , "Not so impressive" , "Became less" , "Lessened" , "reduced" .)
