Caledonian cost adjuster (4)

Ross

I believe the answer is:

scot

I'm a little stuck... Click here to teach me more about this clue!

'caledonian' is the definition.
(I've seen this before)

'cost adjuster' is the wordplay.
'cost' anagrams to 'SCOT'.
However, I am unsure how this is indicated.

Can you help me to learn more?

(Other definitions for scot that I've seen before include "Stevenson was one" , "Native of northern Great Britain" , "Rabbie Burns, for instance" , "Northern member of UK" , "levy, once" .)
