Leading people in good standing are most unlikely to fly (4)
I believe the answer is:
pigs
'most unlikely to fly' is the definition.
I can't tell whether this defines the answer.
'leading people in good standing' is the wordplay.
'leading' says to take the initial letters.
The initial letters of 'people in good standing' is 'PIGS'.
'are' acts as a link.
Can you help me to learn more?
(Other definitions for pigs that I've seen before include "earthenware crocks" , "Farm animals" , "Boars and sows" , "Swine" .)
