Going all the way back, OJ took a vehicle from an Arizonian native (6)
I believe the answer is:
navajo
'vehicle from an arizonian native' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe there's an association between them I don't understand?
'going all the way back oj took a' is the wordplay.
'going all' becomes 'n' (I can't explain this - if you can you should believe this answer much more).
'the way' becomes 'av' (short for avenue).
'back' shows that the letters should be reversed in order.
'took' says to put letters next to each other.
'oj'+'a'='oja'
'oja' in reverse letter order is 'ajo'.
'n'+'av'+'ajo'='NAVAJO'
Can you help me to learn more?
(Other definitions for navajo that I've seen before include "Native American from Arizona, New Mexico or Utah" , "N. American native language" , "A native American Indian people" , "Native American - on Java (anag)" , "A N. American Indian people" .)
