For Inquisition the One Priest (3)
I believe the answer is:
eli
'priest' is the definition.
(biblical figure)
'for inquisition the one' is the wordplay.
'for inquisition' becomes 'e' (I can't explain this - if you can you should give a lot more credence to this answer).
'the one' becomes 'li' (I've seen this in other clues).
'e'+'li'='ELI'
Can you help me to learn more?
(Other definitions for eli that I've seen before include "- Whitney invented the cotton gin in seventeen ninety three" , "Highest priest at Shiloh" , "Man" , "Priest at Shiloh (Samuel)" , "Religious character" .)
