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 an anagram (another form of the same letters).
'sari' is an anagram of 'AIRS'.
'a modest woman wouldn't' acts as a link.
This may not be correct. Some or all of it may be part of 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" .)
