Uproar in crowd in front of the Queen? (6)
I believe the answer is:
ruckus
'uproar' is the definition.
(I've seen this before)
'crowd in front of the queen?' is the wordplay.
'crowd' becomes 'ruck' (I've seen this in other clues).
'in front of' means one lot of letters go next to another.
'the queen?' becomes 'us' (I can't justify this - if you can you should give a lot more credence to this answer).
'ruck'+'us'='RUCKUS'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for ruckus that I've seen before include "Rumpus. commotion" , "Uproar - noisy disturbance" , "Row or commotion" .)
