Since I read all the answers, I'll just give you "it depends". If I was at my local mexican restaurant, it would be tortilla chips. If it was at the mom and pop breakfast joint, it would be a bag of Lays chips. If I was at a chain place like chili's, it would be french fries. Some people now have gotten so bad as to call them "freedom"? Or crisps? A chip is a crunchy thing that comes out of a bag, but doesn't have to be just potato. Doritos are chips, but they're made from tortillas.
