In backward parts of Romania, Germans win again (6)
I believe the answer is:
regain
'win again' is the definition.
('gain' can be a synonym for 'win' so perhaps 'regain' is OK for 'win again')
'in backward parts of romania germans' is the wordplay.
'REGAIN' is hidden backwards in amongst the letters.
However, I'm not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for regain that I've seen before include "Recover, retrieve" , "Get back (previously owned object)" , "Recover - in gear (anag)" , "Possess once more for regina" , "Get back, recover the use of" .)
