Review change in co-ordinates (13)
I believe the answer is:
consideration
'review' is the definition.
(thesaurus)
'change in co-ordinates' is the wordplay.
'change' indicates anagramming the letters.
'in'+'co'+'ordinates'='incoordinates'
'incoordinates' with letters rearranged gives 'CONSIDERATION'.
(Other definitions for consideration that I've seen before include "Study" , "examination" , "factor to be borne in mind" , "Thoughtfulness - relevant factor" , "Bearing in mind - payment" .)
