Consequently return to see the capital (4)
I believe the answer is:
oslo
'the capital' is the definition.
(Oslo is an example)
'consequently return to see' is the wordplay.
'consequently' becomes 'so' ('so' can be a synonym of 'consequently').
'return' shows that the letters should be reversed in order.
'to see' becomes 'lo' (archaic word meaning 'look!').
'so' backwards is 'os'.
'os'+'lo'='OSLO'
(Other definitions for oslo that I've seen before include "Norwegian capital" , "Capital city, called Kristiania until 1924" , "Scandinavian capital" , "Capital often frozen" , "European capital in go-slow" .)
