After game, soldiers in A&E say sorry (9)
I believe the answer is:
apologise
'say sorry' is the definition.
(I've seen this before)
'after game soldiers in ae' is the wordplay.
'after game' becomes 'polo' (polo is a kind of game. I am not sure about the 'after' bit.**).
'soldiers' becomes 'gis' (I've seen this in other clues).
'in' indicates putting letters inside.
'polo'+'gis'='pologis'
'pologis' going into 'ae' is 'APOLOGISE'.
Can you help me to learn more?
(Other definitions for apologise that I've seen before include "Say one is sorry" , "Express regret for a wrong (S, not Z)" , "put things straight" , "Recognise fault" , "Say sorry, my mistake" .)
