Carbon footprint, flash mob and frenemy are among the newest entries in the Merriam-Webster dictionary.
Good News Now has posted 25 of the new entries, along with their meanings and the year in which Webster's researchers first found the words and phrases used in an English-language publication.
The word frenemy has been around since 1977. The concept, however, has been around much longer.
