Assistant ordering Asian menus (10)
I believe the answer is:
amanuensis
'assistant' is the definition.
(amanuensis is a kind of assistant)
'ordering asian menus' is the wordplay.
'ordering' is an anagram indicator.
'asian'+'menus'='asianmenus'
'asianmenus' anagrammed gives 'AMANUENSIS'.
(Other definitions for amanuensis that I've seen before include "stenographer" , "One assisting writer" , "PA" , "who may work with dictator?" , "Literary assistant - scribe" .)
