Yearn to include tales about Biblical region (9)
I believe the answer is:
palestine
'biblical region' is the definition.
'Palestine' can be an answer for 'region' (Palestine is an example). I am not sure about the 'biblical' bit.
'yearn to include tales about' is the wordplay.
'yearn' becomes 'pine' (synonyms).
'to include' is an insertion indicator.
'about' indicates anagramming the letters.
'tales' with letters rearranged gives 'alest'.
'pine' placed around 'alest' is 'PALESTINE'.
Can you help me to learn more?
(Other definitions for palestine that I've seen before include "The historic Holy Land in neat piles" , "Region deriving its name from the Philistines" , "Middle-East area" , "in the Middle East" , "Penalties on region once known as Canaan" .)
