Lack of harmony in ambiance all over the place around central Ireland (9)
I believe the answer is:
imbalance
'lack of harmony' is the definition.
'imbalance' can be an answer for 'lack' (I have seen 'Lack of proportion' mean 'imbalance' so perhaps 'lack' could also mean 'imbalance'). I am not certain of the 'of harmony' bit.
'ambiance all over the place around central ireland' is the wordplay.
'all over the place' indicates anagramming the letters.
'around' indicates putting letters inside.
'central' says to take the centre.
The centre of 'ireland' is 'l'.
'ambiance' anagrammed gives 'imbaance'.
'imbaance' enclosing 'l' is 'IMBALANCE'.
'in' is the link.
Can you help me to learn more?
(Other definitions for imbalance that I've seen before include "Asymmetry" , "Failure of equilibrium" , "Lopsidedness" , "Lack of proportion" , "lack of stability" .)
