Coagulate changes in list (9)
I believe the answer is:
catalogue
'list' is the definition.
(I know that catalogue is a type of list)
'coagulate changes' is the wordplay.
'changes' is an anagram indicator.
'coagulate' with letters rearranged gives 'CATALOGUE'.
'in' is the link.
(Other definitions for catalogue that I've seen before include "From which we order" , "Coagulate into kind of directory" , "(Ilustrated) list of items" , "List of items for sale" , "Record" .)
