She's the real holder of a Biblical title (6)
I believe the answer is:
esther
'biblical title' is the definition.
The definition suggests a singular noun which matches the answer. I also know that 'biblical' relates to this answer.
'she's the real holder of a' is the wordplay.
'ESTHER' is hidden in amongst the letters.
However, I'm not sure how this is indicated.
Can you help me to learn more?
(Other definitions for esther that I've seen before include "10 Heroine" , "religious book" , "Old Testament book telling of a beautiful Jewess" , "Section of Bible" , "Fem. name, threes (anag.)" .)
