Warm oven in outskirts of Turkey (6)
I believe the answer is:
toasty
'warm' is the definition.
(I've seen this in another clue)
'oven in outskirts of turkey' is the wordplay.
'oven' becomes 'oast' (type of kiln).
'in' means one lot of letters goes inside another.
'outskirts of' says to hollow out the word (remove centre letters) (only letters on the outskirts).
'turkey' with its centre removed is 'ty'.
'oast' inserted within 'ty' is 'TOASTY'.
(Other definitions for toasty that I've seen before include "Cosily warm" , "nice and warm?" , "Pleasantly warm" , "Sandwich" , "snack" .)
