Nervous about this parody above all (8)
I believe the answer is:
skittish
'nervous' is the definition.
(I know that nervous can be written as skittish)
'about this parody above all' is the wordplay.
'about' indicates an anagram.
'parody' becomes 'skit' (I've seen this before).
'above all' is a charade indicator (letters next to each other) (some letters go above others).
'this' with letters rearranged gives 'tish'.
'tish' after 'skit' is 'SKITTISH'.
(Other definitions for skittish that I've seen before include "Playful - lively - unpredictable" , "Unpredictably excitable, horses say" , "Playful in coy manner, frisky" , "(Of horses) excessively lively" , "Nervous; playful" .)
