Importunate about change in condition (11)
I believe the answer is:
permutation
'change in condition' is the definition.
'permutation' can be an answer for 'change' (permutation is a kind of change). I am unsure of the 'in condition' bit.
'importunate about' is the wordplay.
'about' indicates an anagram.
'importunate' anagrammed gives 'PERMUTATION'.
Can you help me to learn more?
(Other definitions for permutation that I've seen before include "sort" , "Change of order" , "Changing the arrangement of certain elements" , "Possible ordering (of a number of items)" , "Varied order" .)
