Swinger's type of joint? (5)
I believe the answer is:
hinge
'type of joint?' is the definition.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for hinge that I've seen before include "On what a door swings" , "Door pivot" , "What a door depends upon!" , "Door support" , "Device for letting door etc swing" .)
