Skittish around rig (3)
I believe the answer is:
kit
'rig' is the definition.
(I've seen this in other clues)
'skittish around' is the wordplay.
'around' says the answer is hidden in the clue.
'KIT' can be found hidden inside 'skittish'.
(Other definitions for kit that I've seen before include "In strip" , "Outfit" , "Football top, shorts, stockings and boots?" , "Necessary equipment" , "Young cat" .)
