Not moving electricity (6)
I believe the answer is:
static
I believe this is a double definition.
'not moving' is the first definition.
(I've seen this before)
'electricity' is the second definition.
(static electricity is a kind of electricity)
(Other definitions for static that I've seen before include "Lacking change" , "Motionless like some kind of electricity" , "Inert or passive, like some electricity" , "Still - type of electricity" , "Not moving or changing" .)
