Cost adjuster sometimes called "Jimmy" (4)
I believe the answer is:
scot
'called jimmy' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'cost adjuster sometimes' is the wordplay.
'cost' anagrams to 'SCOT'.
But, I am unsure how this is indicated.
Can you help me to learn more?
(Other definitions for scot that I've seen before include "Eg Aberdonian" , "British northerner" , "Native of Caledonia" , "---- free: originally free from penalties of taxation" , "Glaswegian, say" .)
