Similar sounds in London's city gardens (6)
I believe the answer is:
echoes
'similar sounds in london's' is the definition.
I can't tell whether this defines the answer.
'city gardens' is the wordplay.
'city' becomes 'EC' (the City of London postcode).
'gardens' becomes 'hoes' (I've seen this in another clue).
'ec'+'hoes'='ECHOES'
Can you help me to learn more?
(Other definitions for echoes that I've seen before include "Returning sounds" , "Sound reverberations" , "Reflected sounds" , "Repetitions of sounds" , "Repetition of sounds" .)
