Take in most of cuisine before start of lunch (4)
I believe the answer is:
fool
'take in' is the definition.
(I know that take in can be written as fool)
'most of cuisine before start of lunch' is the wordplay.
'most of' means to remove the last letter.
'cuisine' becomes 'food' (I've seen this in another clue).
'before' means one lot of letters go next to another.
'start of' indicates taking the first letters.
The first letter of 'lunch' is 'l'.
'food' with its last letter removed is 'foo'.
'foo'+'l'='FOOL'
(Other definitions for fool that I've seen before include "Idiot" , "Ass - pudding" , "Nincompoop" , "Jester or silly ass" , "Ass; a dessert" .)
