Flat adverb
From Wikipedia, the free encyclopedia
A flat adverb is an adverb that assumes the form of a related adjective, most often when words ending in -ly are used without the -ly.
The most famous flat adverb may be Apple Computer's "Think Different" campaign. William Safire wrote about the slogan being a flat adverb in a New York Times Magazine column on February 8, 1998.
