Vine for every following Native American (7)
I believe the answer is:
creeper
'vine' is the definition.
(thesaurus)
'every following native american' is the wordplay.
'every' becomes 'per' ('per' means 'for each' or 'for every').
'following' says to put letters next to each other.
'native american' becomes 'cree' (an indigenous people of North America).
'per' after 'cree' is 'CREEPER'.
'for' acts as a link.
(Other definitions for creeper that I've seen before include "soft shoe" , "low-lying plant" , "Climber" , "Liana, vine" , "Plant growing along the ground" .)
