Request: Like different fork (3,3)
I believe the answer is:
ask for
'request' is the definition.
(synonyms)
'like different fork' is the wordplay.
'like' becomes 'as'.
'different' indicates anagramming the letters (letters placed in a different order).
'fork' is an anagram of 'kfor'.
'as'+'kfor'='ASK FOR'
(Other definitions for ask for that I've seen before include "Demand" , "Make a request" .)
