Woman and another returning capital (6)
I believe the answer is:
vienna
'capital' is the definition.
(capital of Austria)
'woman and another returning' is the wordplay.
'woman' becomes 'Vi' (short for Violet).
'and' means one lot of letters go next to another.
'another' becomes 'anne' (I can't justify this - if you can you should give a lot more credence to this answer).
'returning' says the letters should be written in reverse.
'anne' backwards is 'enna'.
'vi'+'enna'='VIENNA'
Can you help me to learn more?
(Other definitions for vienna that I've seen before include "Capital on the Danube Canal" , "Austria's capital city" , "Wien" , "Austrian capital" , "On the Danube, it was home to many great composers" .)
