Substitution of ten clips made badly (12)
I believe the answer is:
displacement
'substitution' is the definition.
(displacement is a kind of substitution)
'ten clips made badly' is the wordplay.
'badly' is an anagram indicator.
'ten'+'clips'+'made'='tenclipsmade'
'tenclipsmade' is an anagram of 'DISPLACEMENT'.
'of' acts as a link.
(Other definitions for displacement that I've seen before include "Measure of ship's size" , "Shift in position" , "Amount of movement" .)
