Some lychees expected in Caerphilly? (6)
I believe the answer is:
cheese
'caerphilly?' is the definition.
(I've seen this before)
'some lychees expected 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 expected in'.
(Other definitions for cheese that I've seen before include "Produce created from milk curds" , "Gloucester or Emmental, say" , "A big one would be important" , "Soft or more solid creamy food" , "Gloucester or Edam, say" .)
