Fireplace within kept in gleaming condition (5)
I believe the answer is:
ingle
'fireplace' is the definition.
(I've seen this in another clue)
'within kept in gleaming condition' is the wordplay.
I cannot really see how this works, but
'within' could be 'in' and 'in' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for ingle that I've seen before include "Catamite" , "Kind of fireplace - get leg in" , "Warm corner" , "Fireplace (mainly dialect)" , "Hearth" .)
