Joint approach in general stores (5)

I believe the answer is:

hinge

'joint' is the definition.
(hinge joint is a kind of joint)

'approach in general stores' is the wordplay.
'stores' indicates the answer is hidden within the clue.
'HINGE' can be found hidden inside 'approach in general'.

(Other definitions for hinge that I've seen before include "Moveable joint" , "Door pivot" , "Fastening for door etc" , "Joint on which things turn" , "Joint on which something turns" .)

I've seen this clue in The Times.
