In which a lady could give herself airs? (4)
I believe the answer is:
sari
'in which a lady could' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'herself airs?' is the wordplay.
'airs' can be anagrammed to 'SARI'.
However, I'm not clear how this is indicated.
'give' acts as a link.
Can you help me to learn more?
(Other definitions for sari that I've seen before include "Indian costume" , "Eastern garment" , "Traditional Indian women's dress" , "South Asian garment (variant spelling)" , "Hindu woman's dress" .)
