Victor taking a girl on the river (5)
I believe the answer is:
volga
'the river' is the definition.
(Volga is an example)
'victor taking a girl' is the wordplay.
'victor' becomes 'v' (phonetic alphabet: alpha, bravo, charlie etc.).
'taking' says to put letters next to each other.
'a girl' becomes 'olga' (**).
'v'+'olga'='VOLGA'
'on' is the link.
(Other definitions for volga that I've seen before include "River at Astrakhan" , "River flowing into the Caspian Sea" , "Major Russian river" , "flow of water" , "Europe's longest river" .)
