States further that hundreds are in sad disarray (4)
I believe the answer is:
adds
'states further' is the definition.
(I've seen this in another clue)
'hundreds are in sad disarray' is the wordplay.
'hundreds' becomes 'd' (I've seen this in other clues).
'are in' is an insertion indicator.
'disarray' indicates anagramming the letters.
'sad' is an anagram of 'ads'.
'd' placed within 'ads' is 'ADDS'.
'that' acts as a link.
(Other definitions for adds that I've seen before include "Reckons" , "Calculates the sum" , "Supplements" , "Finds the sum (4)," , "Tots up" .)
