Allegiance, commitment (7)
I believe the answer is:
loyalty
I believe this is a double definition.
'allegiance' is the first definition.
(I've seen this in another clue)
'commitment' is the second definition.
(I know that commitment can be written as loyalty)
(Other definitions for loyalty that I've seen before include "Alligiance and fidelity" , "Faithfully allegiance" , "Dedication" , "Strong allegiance" , "Firmness of allegiance" .)
