Generification is the use of specific brand names of products as names for the products in general.

In numerous cases over the past century, the colloquial use of a brand name as a generic term has led to the loss of a company's right to the exclusive use of that brand name. The legal term for this is genericide.

For example, the common nouns aspirin, yo-yo, and trampoline were once legally protected trademarks. (In many countries-but not in the United States or the United Kingdom-Aspirin remains a registered trademark of Bayer AG.)

Etymology: From the Latin, "kind"

Generification and Dictionaries

"A surprising number of words have developed contentious generic meanings: they include aspirin, band-aid, escalator, filofax, frisbee, thermos, tippex, and xerox. And the problem facing the lexicographer dictionary-maker is how to handle them. If it is everyday usage to say such things as I have a new hoover: it's an Electrolux, then the dictionary, which records everyday usage, should include the generic sense. The principle has been tested several times in the courts and the right of the dictionary-makers to include such usages is repeatedly upheld. But the decision still has to be made: when does a proprietary name develop a sufficient general usage to be safely called generic?"

From Brand Names to Generic Terms

These words below have gradually slipped from brand names to generic terms:

  • Elevator and escalator were both originally trademarks of the Otis Elevator Company.
  • Zipper: A name given to a 'separable fastener' by the B.F. Goodrich Company many years after it was invented. The new name helped the zipper attain popularity in the 1930s.
