Commotion concerning steak given to us (6)
I believe the answer is:
rumpus
'commotion' is the definition.
(I know that commotion can be written as rumpus)
'steak given to us' is the wordplay.
'steak' becomes 'rump' (rump steak is a kind of steak).
'given to' means one lot of letters go next to another.
'rump'+'us'='RUMPUS'
'concerning' acts as a link.
(Other definitions for rumpus that I've seen before include "To-do" , "Tumult" , "Noisy disturbance" , "Harsh rough nature" , "'Commotion, din (6)'" .)
