List of some prime numbers (4)
I believe the answer is:
menu
'list' is the definition.
(list of dishes)
'some prime numbers' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'MENU' is hidden in the letters of 'prime numbers'.
'of' is the link.
(Other definitions for menu that I've seen before include "List of food items on offer" , "Tariff" , "Choice of dishes" , "that can appear on computer screen" , "choice of food" .)
