Damaged nose parts change position (9)
I believe the answer is:
transpose
'change position' is the definition.
(transpose can mean to change position)
'damaged nose parts' is the wordplay.
'damaged' indicates anagramming the letters.
'nose'+'parts'='noseparts'
'noseparts' with letters rearranged gives 'TRANSPOSE'.
(Other definitions for transpose that I've seen before include "Change to a different key" , "switch" , "Change places with patroness" , "show skill at keyboard?" , "Change the order or arrangement of" .)
