Tito ends at Georgia in old robe (4)
I believe the answer is:
toga
'old robe' is the definition.
'toga' can be an answer for 'robe' (I have seen 'Roman robe ' mean 'toga' so perhaps 'robe' could also mean 'toga'). I'm not sure about the 'old' bit.
'tito ends at georgia' is the wordplay.
'ends' means to remove the middle letters.
'at' is a charade indicator (letters next to each other).
'georgia' becomes 'ga'.
'tito' with its middle taken out is 'to'.
'to'+'ga'='TOGA'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for toga that I've seen before include "This ancient robe might get your goat" , "draped cloth" , "Roman dress" , "Roman gents' cloak" , "Graph's y value" .)
