Amerindian's north-eastern land, lush all around (9)
I believe the answer is:
winnebago
'amerindian's' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see an association between them that I don't see?
'north-eastern land lush all around' is the wordplay.
'north eastern' becomes 'NE' (abbreviation).
'land' becomes 'bag' (I've seen this in other clues).
'lush' becomes 'wino' (I've seen this in another clue).
'all around' is an insertion indicator.
'ne'+'bag'='nebag'
'nebag' put into 'wino' is 'WINNEBAGO'.
Can you help me to learn more?
(Other definitions for winnebago that I've seen before include "Indian" , "Native American" , "Brave" , "Popular US motor home manufacturer" , "Wisconsin lake" .)
