What’s said to raise a smile in Cheshire? (6)
I believe the answer is:
cheese
This clue is a double definition.
'what's said to raise a smile' is the first definition.
('say cheese!')
'cheshire?' is the second definition.
(as in a Cheshire cheese)
'in' is the link.
(Other definitions for cheese that I've seen before include "Nautical peaked cap - board with wire attached" , "Big one's important" , "Brie or Emental, say" , "Edam or cheddar, say" , "Feta, for example" .)
