Take in the dessert (4)
I believe the answer is:
fool
I believe this is a double definition.
'take in' is the first definition.
('fool' can be a synonym of 'take in')
'the dessert' is the second definition.
(I've seen this before)
(Other definitions for fool that I've seen before include "One and his money are soon parted" , "` `More people know Tom .... that Tom .... knows' '" , "Dessert of pureed fruit and cream" , "Jester - dessert" , "Trifle" .)
