Army doctor has barge in Eastern European capital? (6)
I believe the answer is:
moscow
'european capital?' is the definition.
(capital of Russia)
'army doctor has barge' is the wordplay.
'army doctor' becomes 'mo' (medical officer).
'has' says to put letters next to each other.
'barge' becomes 'scow' (scow is a kind of barge).
'mo'+'scow'='MOSCOW'
'in eastern' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for moscow that I've seen before include "Olympic city, 1980" , "Russian city" , "Kremlin location" , "Capital of Russia" , "capital city" .)
