Extremely fine admiral totally generates strong allegiance (6)
I believe the answer is:
fealty
'allegiance' is the definition.
(I know that allegiance can be written as fealty)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for fealty that I've seen before include "The loyalty that citizens owe their country" , "expression of commitment" , "Loyalty to feudal superior" , "Loyalty or allegiance as once to lord" , "Vassal's sworn loyalty to a lord (historical)" .)
