One that might leave fingerprint on priest (5)
I believe the answer is:
padre
This could be a double definition.
'one that might leave fingerprint' is the first definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'priest' is the second definition.
(Padre is an example)
'on' acts as a link.
Can you help me to learn more?
(Other definitions for padre that I've seen before include "Minister" , "Army chaplain" , "Cleric" , "A military clergyman" , "Father" .)
