Curiosity of Queen’s NI visit is kicked around (15)
I believe the answer is:
inquisitiveness
'curiosity' is the definition.
(inquisitiveness is a kind of curiosity)
'of queen's ni visit is kicked around' is the wordplay.
'of' is an anagram indicator (the answer comes from or 'of' the letters).
'is kicked' becomes 'iss' (I am not sure about this - if you are sure you should believe this answer much more).
'around' indicates putting letters inside.
'queen'+'ni'+'visit'='queennivisit'
'queennivisit' with letters rearranged gives 'nquisitivene'.
'nquisitivene' placed within 'iss' is 'INQUISITIVENESS'.
Can you help me to learn more?
(Another definition for inquisitiveness that I've seen is " Interest in".)
