Raising one's glass in honour of police operation? (8)
I believe the answer is:
toasting
'raising one's glass' is the definition.
(I've seen this before)
'honour of police operation?' is the wordplay.
'honour of' becomes 'toa' (I can't explain this - if you can you should give a lot more credence to this answer).
'police operation?' becomes 'sting' (sting can mean a police operation).
'toa'+'sting'='TOASTING'
'in' is the link.
Can you help me to learn more?
(Other definitions for toasting that I've seen before include "Browning" , "Raising one's glass" , "Drinking a health to" , "Raising glasses" .)
