She's in the dumps and rather disconsolate (6)
I believe the answer is:
sandra
'she's' is the definition.
'in the dumps and rather disconsolate' is the wordplay.
'in' indicates the answer is hidden within the clue.
'SANDRA' can be found hidden inside 'dumps and rather disconsolate'.
(Other definitions for sandra that I've seen before include "Girl's name" , "woman's name" , "So woman" , "girl" .)
