Needlework is displayed in the south-east part of the building (6)
I believe the answer is:
sewing
'needlework' is the definition.
(I know that sewing is a type of needlework)
'south-east part of the building' is the wordplay.
'south east' becomes 'SE' (abbreviation).
'part of the building' becomes 'wing' ('wing' is part of 'building').
'se'+'wing'='SEWING'
'is displayed in the' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for sewing that I've seen before include "Needlework" , "Darning" , "Joining by stitching" , "Using a needle and thread" , "Working with a needle" .)
