Shy singer picked up in French city (6)
I believe the answer is:
rennes
'french city' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for rennes that I've seen before include "French city" , "City of NW France" , "City of Brittany" , "Hurries" , "Major town in Brittany" .)
