Speak about a devout heart, somewhere in France (5)
I believe the answer is:
savoy
'in france' is the definition.
(I know that Savoy has the is part of France)
'speak about a devout heart' is the wordplay.
'speak' becomes 'say' (I've seen this in another clue).
'about' is an insertion indicator.
'heart' says to take the centre.
The middle letters of 'devout' are 'vo'.
'say' enclosing 'vo' is 'SAVOY'.
'somewhere' is the link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for savoy that I've seen before include "Type of cabbage - London theatre" , "Cabbage; hotel" , "area of France" , "Variety of cabbage" , "A cabbage; some Operas" .)
