Extraordinary reduction present (9)
I believe the answer is:
introduce
'present' is the definition.
(introducing is a kind of presenting)
'extraordinary reduction' is the wordplay.
'extraordinary' indicates an anagram.
'reduction' with letters rearranged gives 'INTRODUCE'.
(Other definitions for introduce that I've seen before include "Present to another or bring up for discussion" , "Bring into use by way of reduc tion" , "Bring to notice or make known" , "Start; present" , "Present, make known" .)
