Sheep in more disarray (6)
I believe the answer is:
merino
'sheep' is the definition.
(breed of sheep)
'in more disarray' is the wordplay.
'disarray' indicates anagramming the letters.
'in'+'more'='inmore'
'inmore' with letters rearranged gives 'MERINO'.
(Other definitions for merino that I've seen before include "Sheep from Spain with a heavy quality fleece" , "Fine woollen yarn" , "Can this sheep be found in Rome?" , "Sheep bred for its long, fine wool" , "Type of sheep" .)
