Egotistic American attached to endless fluffy adornment (7)
I believe the answer is:
pompous
'egotistic' is the definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
'american attached to endless fluffy adornment' is the wordplay.
I cannot quite see how this works, but
'american' could be 'us' and 'us' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for pompous that I've seen before include "Vain" , "Affectedly self-important" , "Affectedly grand" , "Bombastic" , "Arrogant" .)
