Where to stay awhile, quietly by the river (4)
I believe the answer is:
camp
'where to stay awhile' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'quietly by the river' is the wordplay.
'quietly' becomes 'p' (p for piano and quiet).
'by' is a charade indicator (letters next to each other).
'the river' becomes 'cam' (river in Cambridge, England).
'p' put after 'cam' is 'CAMP'.
Can you help me to learn more?
(Other definitions for camp that I've seen before include "Distance down" , "holiday venue" , "Extensive outdoor facility" , "prehistoric site" , "Effeminate; military base" .)
