Claim of fairy alone, not one seen as “queenly” (8)
I believe the answer is:
imperial
'queenly' is the definition.
(thesaurus)
'claim of fairy alone not one' is the wordplay.
'claim of fairy' becomes 'imperia' (I am not sure about this - if you are sure you should believe this answer much more).
'alone' becomes 'lone' (synonyms).
'not' suggests deleting specific letters.
'lone' with 'one' removed is 'l'.
'imperia'+'l'='IMPERIAL'
'seen as' is the link.
(Other definitions for imperial that I've seen before include "Majestic - wine bottle" , "Magnificent; small pointed beard" , "Related to empire" , "Sovereign - old Russian gold coin - type of beard" , "I prime Al to describe the rule of great territories" .)
