Religious book whose author conceals its name (5)
I believe the answer is:
hosea
'religious book' is the definition.
'hosea' can be an answer for 'book' (book of the Hebrew Bible). I'm not certain of the 'religious' bit.
'whose author conceals its name' is the wordplay.
'HOSEA' is hidden within the letters.
But, I'm not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for hosea that I've seen before include "Book of prophecies" , "author of verse collection" , "Book writer" , "OT prophet" , "bookmaker" .)
