Big part of Chad (6)

I believe the answer is:

sahara

(Other definitions for sahara that I've seen before include "Uncultivated region of north Africa" , "Great desert in N Africa" , "North African desert" , "World's largest sandy area" , "Great African desert" .)

I've seen this clue in The Washington Post.
