Tent fire spread by current queen (9)
I believe the answer is:
nefertiti
'queen' is the definition.
(I know that Nefertiti has the occupation queen regnant)
'tent fire spread by current' is the wordplay.
'spread' is an anagram indicator.
'by' means one lot of letters go next to another.
'current' becomes 'I' (physics symbol).
'tent'+'fire'='tentfire'
'tentfire' with letters rearranged gives 'nefertit'.
'nefertit'+'i'='NEFERTITI'
(Other definitions for nefertiti that I've seen before include "Queen on the Nile" , "Oddly, the Egyptian queen is an entire fit" , "Beautiful queen who ruled Egypt with the Pharaoh" , "Egyptian queen, the wife of Akhenaton" , "Egyptian beauty queen" .)
