Female with such social standing is candid of expression (4)
I believe the answer is:
rank
'female with such social standing' is the definition.
'rank' can be an answer for 'standing' (as in social standing or rank). I am unsure of the 'female with such social' bit.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for rank that I've seen before include "Excessive" , "Coarse; tier" , "High social standing" , "fare might be found here" , "Complete" .)
