Some lychees exposed in Brie? (6)
I believe the answer is:
cheese
'brie?' is the definition.
(brie is a kind of cheese)
'some lychees exposed in' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'CHEESE' can be found hidden inside 'lychees exposed in'.
(Other definitions for cheese that I've seen before include "Product of milk curds" , "Eg, Limburger" , "Edam, Brie, Cheddar..." , "Gloucester or Emmental, say" , "Eg, Camembert" .)
