Swinging round part of the house (4)
I believe the answer is:
'the house' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'swinging round part' is the wordplay.
'part' says the answer is hidden in the clue.
'WING' is hidden in the letters of 'swinging round'.
'of' is the link.
Can you help me to learn more?
(Other definitions for wing that I've seen before include "Appendage aiding flight" , "Arm of building or bird" , "Wound superficially; part of large house" , "Limb - faction" , "Group of squadrons; par of car" .)
