Swinging round part of the house (4)
I believe the answer is:
wing
'the house' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'swinging round part' is the wordplay.
'part' says the answer is hidden in the clue.
'WING' is hidden within 'swinging round'.
'of' acts as a 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" .)
