All of America cross-legged (5)
I believe the answer is:
lotus
'all of america cross-legged' is the definition.
I can't tell whether this defines the answer.
'all of america' is the wordplay.
'all of' becomes 'lot' (I can't justify this - if you can you should believe this answer much more).
'america' becomes 'US' (United States).
'lot'+'us'='LOTUS'
Can you help me to learn more?
(Other definitions for lotus that I've seen before include "Tropical water-lily" , "Mythical fruit inducing state of luxurious dreaminess" , "Reason for forgetfulness" , "Car manufacturer - plant" , "reason for indolence" .)
