Police scared a lot of priests (10)
I believe the answer is:
sacerdotal
'police scared a lot of priests' is the definition.
I can't judge whether this definition defines the answer.
'police scared a lot' is the wordplay.
'police' indicates an anagram (police can mean to control or manage).
'scared'+'a'+'lot'='scaredalot'
'scaredalot' with letters rearranged gives 'SACERDOTAL'.
Can you help me to learn more?
(Other definitions for sacerdotal that I've seen before include "priestly" , "concerning priests" .)
