Some nude content that's seen on lots of web pages (4)
I believe the answer is:
menu
'seen on lots of web pages' is the definition.
I can't tell whether this definition defines the answer.
'some nude content' is the wordplay.
'content' indicates a hidden word (I've seen 'content of' mean this).
'MENU' can be found hidden inside 'some nude'.
'that's' is the link.
Can you help me to learn more?
(Other definitions for menu that I've seen before include "Options available" , "Tariff" , "Bill of fare" , "List of dishes offered by restaurant" , "List of food items on offer" .)
