Broadcast returns with two German couples in resort area (7)
I believe the answer is:
riviera
'resort area' is the definition.
(I've seen this before)
'broadcast returns with two german couples' is the wordplay.
'broadcast' becomes 'air' (to air on TV).
'returns' says the letters should be written backwards.
'with' is an insertion indicator.
'two german couples' becomes 'vier' (I can't explain this - if you can you should believe this answer much more).
'air' written backwards gives 'ria'.
'ria' going around 'vier' is 'RIVIERA'.
'in' is the link.
Can you help me to learn more?
(Other definitions for riviera that I've seen before include "Subtropical 1 dn area" , "popular holiday area" , "Med coastal region" , "French/Italian Med. coast" , "place on the Med" .)
