Some made dire decision -- about to be mocked (7)
I believe the answer is:
derided
'be mocked' is the definition.
(I've seen this before)
'some made dire decision about' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'about' says the letters should be written backwards.
'dedired' is hidden in the letters of 'made dire decision'.
'dedired' written backwards gives 'DERIDED'.
'to' acts as a link.
(Other definitions for derided that I've seen before include "Scorned" , "Made fun of" , "Treated or spoke of with contempt" , "Mocked, laughed at" , "Ridiculed" .)
