Type of free Caledonian (4)
I believe the answer is:
scot
This could be a double definition.
'type of free' is the first definition.
'scot' can be an answer for 'free' (thesaurus). I am not certain of the 'type of' bit.
'caledonian' is the second definition.
(I've seen this in other clues)
Can you help me to learn more?
(Other definitions for scot that I've seen before include "Rabbie Burns, for instance" , "---- free: originally free from penalties of taxation" , "Native of Inverness" , "9 [KEIR HARDIE], say" , "Ancient tax" .)
