Sort meal out with medium confusion (9)
I believe the answer is:
maelstrom
'confusion' is the definition.
(I've seen this before)
'sort meal out with medium' is the wordplay.
'out with' indicates anagramming the letters (out can mean wrong or inaccurate).
'medium' becomes 'm' (as in UK clothing sizes).
'sort'+'meal'='sortmeal'
'sortmeal' anagrammed with 'm' can make 'MAELSTROM'.
(Other definitions for maelstrom that I've seen before include "violent upheaval" , "Whirlpool, turmoil" , "Strong circular current of water" , "disorder" , "Norwegian whirlpool" .)
