Cord; bend (4)
I believe the answer is:
flex
This clue is a double definition.
'cord' is the first definition.
(I have seen 'Bendable cord ' mean 'flex' so perhaps 'cord' could also mean 'flex')
'bend' is the second definition.
(I know that bend can be written as flex)
(Other definitions for flex that I've seen before include "Insulated wire cable" , "Bend - electrical cable" , "Bend; electric lead" , "Electrical power cord" , "Bend (muscle?)" .)
