A list men turn to (4)
I believe the answer is:
menu
'a list' is the definition.
(menu is a kind of list)
'men turn to' is the wordplay.
'turn to' becomes 'u' (I can't explain this - if you can you should believe this answer much more).
'men'+'u'='MENU'
Can you help me to learn more?
(Other definitions for menu that I've seen before include "Tariff" , "Carte du jour" , "restaurant guide" , "Choice of dishes" , "List of dishes on offer" .)
