Dark gangster comes after king for award (10)
I believe the answer is:
knighthood
'award' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'dark gangster comes after king' is the wordplay.
'dark' becomes 'night' (it's dark at nighttime).
'gangster' becomes 'hood' (I've seen this in another clue).
'comes after' means one lot of letters go next to another.
'king' becomes 'K' (abbreviation for king in chess).
'night'+'hood'='nighthood'
'nighthood' put after 'k' is 'KNIGHTHOOD'.
'for' is the link.
Can you help me to learn more?
(Other definitions for knighthood that I've seen before include "High honour" , "Order of chivalry" , "bishop's neighbour" , "Title" .)
