Reproduce pace, taking European clip out (9)
I believe the answer is:
replicate
'reproduce' is the definition.
(I know that replicate is a more specific form of the action reproduce)
'pace taking european clip out' is the wordplay.
'pace' becomes 'rate' (synonyms).
'taking' means one lot of letters goes inside another.
'european' becomes 'e' (abbreviation e.g. EU).
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'e'+'clip'='eclip'
'eclip' with letters rearranged gives 'eplic'.
'rate' enclosing 'eplic' is 'REPLICATE'.
(Other definitions for replicate that I've seen before include "Copy, reproduce" , "Copy exactly" , "Make an exact copy of" .)
