Suddenly moved back from playground that's greasy (8)
I believe the answer is:
recoiled
'suddenly moved back' is the definition.
'playground that's greasy' is the wordplay.
'playground' becomes 'rec' (I've seen this in other clues).
'that's greasy' becomes 'oiled' (I've seen this before).
'rec'+'oiled'='RECOILED'
'from' acts as a link.
(Other definitions for recoiled that I've seen before include "Drew back in disgust or fear" , "Shrank back in horror" , "Sprang back suddenly in fear or disgust" , "Drew back in horror" , "Flinched or sprang back" .)
