Overseer's excellent intent: end intervention (14)
I believe the answer is:
superintendent
'overseer's' is the definition.
(synonyms)
'excellent intent end intervention' is the wordplay.
I cannot really see how this works, but
'excellent' could be 'super' (I've seen this in another clue) and 'super' is located in the answer.
'intent' could be 'end' (I've seen this in other clues) and 'end' is found within the answer.
'end' could be 'intent' (intent is a kind of end) and 'intent' is found in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for superintendent that I've seen before include "Police rank" , "Police chief" , "One who is in charge of an organisation" , "Senior police officer" , "Overseer; police officer" .)
