Determined to have fire in south attended to (6-6)
I believe the answer is:
single-minded
'determined' is the definition.
(I've seen this before)
'fire in south attended to' is the wordplay.
I cannot quite understand how this works, but
'fire' could be 'ingle' (ingle means a fireplace) and 'ingle' is present in the answer.
'in' is present in the answer.
'south' could be 's' (abbreviation) and 's' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'to have' acts as a link.
Can you help me to learn more?
(Other definitions for single-minded that I've seen before include "Determined" , "Mentally focussed" , "Dedicated to one outcome" , "Concentrating on one particular thing" , "Concentrating on only one aim" .)
