It's played with much love (4)
I believe the answer is:
faro
'it's played' is the definition.
I can't tell whether this defines the answer.
'with much love' is the wordplay.
'with' means one lot of letters go next to another.
'much' becomes 'far' (I've seen this in other clues).
'love' becomes 'o' (love means zero in tennis).
'far'+'o' is 'FARO'.
Can you help me to learn more?
(Other definitions for faro that I've seen before include "Portuguese seaport" , "Algarve seaport" , "Card game - Algarve port" , "Portuguese city" , "Portuguese, 22 [RESORT]" .)
