Franklin! Georgia left part of divided India! (6)
I believe the answer is:
bengal
'part of divided india' is the definition.
'bengal' can be an answer for 'part' (I have seen 'part of India' mean 'bengal' so perhaps 'part' could also mean 'bengal'). I'm not certain of the 'of divided india' bit.
'franklin georgia left' is the wordplay.
'franklin' becomes 'ben' (I've seen this in another clue).
'georgia' becomes 'GA' (abbreviation for the US state).
'left' becomes 'l' (common abbreviation).
'ben'+'ga'+'l'='BENGAL'
Can you help me to learn more?
(Other definitions for bengal that I've seen before include "... Bay area" , "Bay of - lies between India and Myanmar" , "'The tiger is a gal, Ben (6)'" , "Subcontinental region" , "Former province now divided between India and Bangladesh" .)
