This meat served at midday meal? (8)
I believe the answer is:
luncheon
'midday meal?' is the definition.
(I've seen this before)
'this meat served at' is the wordplay.
'this meat' becomes 'lunch' (lunch meat is a kind of meat).
'served at' becomes 'eon' (I can't explain this - if you can you should believe this answer much more).
'lunch'+'eon'='LUNCHEON'
Can you help me to learn more?
(Other definitions for luncheon that I've seen before include "fare at one?" , "Midday meal" , "Food" , "midday menu" , "part of formal board" .)
