'native american's' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.

'needs grew after development' is the wordplay.
'after' says to put letters next to each other.
'development' is an anagram indicator.
'needs'+'grew'='needsgrew'
'needsgrew' anagrammed gives 'SEDGE-WREN'.
