Consolidates, unusually low (12)
I believe the answer is:
disconsolate
'low' is the definition.
(I've seen this before)
'consolidates unusually' is the wordplay.
'unusually' indicates anagramming the letters.
'consolidates' with letters rearranged gives 'DISCONSOLATE'.
(Other definitions for disconsolate that I've seen before include "Stuck with the blues" , "Low in spirits" , "Unhappy and unable to be comforted" , "Melancholy" , "Dejected" .)
