Present poorly made reduction (9)
I believe the answer is:
introduce
'present' is the definition.
(I know that present can be written as introduce)
'poorly made reduction' is the wordplay.
'poorly made' indicates an anagram.
'reduction' is an anagram of 'INTRODUCE'.
(Other definitions for introduce that I've seen before include "Bring into use by way of reduc tion" , "Make one person known to another" , "Provide an opening announcement for" , "Bring in for the first time" , "Present, make known" .)
