The flying dean? (5)
I believe the answer is:
swift
This clue might be a double definition.
'the flying' is the first definition.
(I've seen this before)
'dean?' is the second definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
Can you help me to learn more?
(Other definitions for swift that I've seen before include "Swallow-like bird" , "Jonathan ..., clergyman and satirist" , "Quick-moving" , "Large property" , "Rapid - writer - bird" .)
