korien_mar31_pixabayWhat’s English for a plastic bandage you can put on a small cut? Not Band-Aid—that’s a brand name. It’s just so popular that many people don’t know any other name for that kind of bandage.

This has happened to many brands. Kleenex has become a word for any facial tissue. Xerox can be used to mean “copy”. Some people call any soda by the name Coke. Velcro is actually only one brand of “magic tape”, but there’s no other word to describe it clearly and quickly.
