This part of the house is in an area under cover and airy (7)
I believe the answer is:
veranda
'this part of the house is' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'an area under cover and airy' is the wordplay.
'an area' says the answer is hidden in the clue (I've seen 'area of' mean this (I've seen this in other clues)).
'VERANDA' can be found hidden inside 'under cover and airy'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for veranda that I've seen before include "Roofed platform adjoining a house" , "Addition to a house" , "Open roofed platform" , "Covered porch on building" , "Porch along the outside of a building" .)
