River flowing though Heidelberg? (4)
I believe the answer is:
elbe
'river' is the definition.
(river in Germany)
'flowing though heidelberg?' is the wordplay.
'ELBE' is hidden in amongst the letters.
But, I am uncertain how this is indicated.
Can you help me to learn more?
(Other definitions for elbe that I've seen before include "Dresden and Hamburg's river" , "European river" , "A major German river" , "Current" , "It flows through Germany" .)
