Going for a “chick flick” tonight? Consult a dictionary first.

All right word fans, what do “brain freeze,” “chick flick,” “hospitalist,” “otology,” and “amuse-bouche” all have in common? They’re among the 18 new word entries in the latest printed edition of the Merriam-Webster’s Collegiate Dictionary. They join the roughly 17 million other words that the dictionary publisher monitors, a few of which make it into their amalgum of words of the American language.

New words take about 10 years to get into the dictionary. Some are more urgent to get in that others, like “SARS,” which stands for Severe Acute Respiratory Syndrome. This acronym began attracting attention two years ago as a health hazard, but is of such consequence to American readers that the publishers decided to add it this year. The last update to the Merriam-Webster Collegiate Dictionary in print was in 2003.

These new words haven’t begun to show up in the Merriam-Webster online dictionary, however.
