Playing with string in feline agreement (9)
I believe the answer is:
concordat
'agreement' is the definition.
(concordat is a kind of agreement)
'playing with string in feline' is the wordplay.
'playing with' becomes 'on' (on can mean playing or performing. I am not sure about the 'with' bit.).
'string' becomes 'cord' (I've seen this in another clue).
'in' means one lot of letters goes inside another.
'feline' becomes 'cat' (cat is a kind of feline).
'on'+'cord'='oncord'
'oncord' inserted inside 'cat' is 'CONCORDAT'.
Can you help me to learn more?
(Other definitions for concordat that I've seen before include "Agreement with Rome" , "Signed agreement" , "pact" , "papal blessing" .)
