Perhaps Queen fan is inspired by improvisation of Taylor (8)
I believe the answer is:
royalist
'perhaps queen fan' is the definition.
I can't judge whether this definition defines the answer.
'is inspired by improvisation of taylor' is the wordplay.
'inspired by' means one lot of letters goes inside another (some letters breathed in or 'inspired' by others).
'improvisation of' is an anagram indicator (I've seen this in other clues).
'taylor' is an anagram of 'royalt'.
'is' inserted within 'royalt' is 'ROYALIST'.
Can you help me to learn more?
(Other definitions for royalist that I've seen before include "rightwinger?" , "Monarch's supporter" , "opponent of Republicans" , "Civil War Cavalier" , "Civil War participant" .)
