The price to a careless Scot? (4)
I believe the answer is:
cost
'the price' is the definition.
('cost' can be a synonym of 'price')
'a careless scot?' is the wordplay.
'a careless' is an anagram indicator.
'scot' with letters rearranged gives 'COST'.
'to' acts as a link.
(Other definitions for cost that I've seen before include "Fee" , "Be priced at" , "Amount required as payment" , "penalty" , "Suffering" .)
