Iroquoian language (7)
'iroquoian language' is the definition.
(Mohawk is an example)
This is the entire clue.
(Other definitions for mohawk that I've seen before include "Native American - punk hairdo" , "Skating manoeuvre - member of Amerindian tribe" , "Member of a native American people and a haircut" , "(N Amer.) Indian" , "American native; skating step" .)
