The list object has a name, mylist.
The three objects inside the list have n
k.
Sometimes brand names do become generic. "Personal Computer" once was a
specific IBM model, not just a description. Elevator and escalator were
once brandnames. In some parts of the southern USA, "coke" is used as a
word for any softdrink, not just Coca Cola.
