Firm in Russian city concerning for Scotland (9)
I believe the answer is:
permanent
'firm' is the definition.
(thesaurus)
'russian city concerning for scotland' is the wordplay.
I cannot quite understand how this works, but
'city' could be 'perm' (Perm is an example) and 'perm' is present in the answer.
'concerning' could be 'anent' (I've seen this before) and 'anent' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for permanent that I've seen before include "Lasting, unchangeable" , "Lasting indefinitely" , "indestructible" , "full-time" , "Everlasting" .)
