Form of sari a modest woman wouldn’t put on (4)
I believe the answer is:
airs
'put on' is the definition.
(thesaurus)
'form of sari' is the wordplay.
'form of' indicates anagramming the letters (the letters need to be in another 'form').
'sari' anagrammed gives 'AIRS'.
'a modest woman wouldn't' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for airs that I've seen before include "Arrogance" , "Attitudes or tunes" , "Melodies or artificial manners" , "Haughty affectation" , "Broadcasts" .)
