Desire to acquire Greenland without at first notifying loyal allied nations (5)
I believe the answer is:
greed
'desire' is the definition.
(greed is a kind of desire)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for greed that I've seen before include "Gluttony" , "Insatiability" , "Immoderate desire" , "sin" , "Wanting too much" .)
