Despicable type almost finished (6)
I believe the answer is:
sordid
'despicable' is the definition.
(thesaurus)
'type almost finished' is the wordplay.
'type' becomes 'sort' (I've seen this before).
'almost' means to remove the last letter (most of the word but not all of it).
'finished' becomes 'did' (do can mean to complete or finish).
'sort' with its last letter taken off is 'sor'.
'sor'+'did'='SORDID'
(Other definitions for sordid that I've seen before include "Dirty, depressing and squalid" , "Morally revolting" , "Seedy, squalid" , "meanness" , "Seedy, foul" .)
