Separate new Easter egg (9)
I believe the answer is:
segregate
'separate' is the definition.
(segregating is a kind of separating)
'new easter egg' is the wordplay.
'new' indicates anagramming the letters.
'easter'+'egg'='easteregg'
'easteregg' anagrammed gives 'SEGREGATE'.
(Other definitions for segregate that I've seen before include "Put apart from others for easter egg" , "Cut off" , "split" , "Separate by race or religion" , "Easter-egg (anag.)" .)
