REST stands for Representational State Transfer. Acronym purists often write it as ReST, because the E in REST does not actually stand for anything. It is merely the second letter of the word representational. This prevents controversy on how to pronounce it, like the one that has plagued GIF in recent years. With the E included, there is no confusion when pronouncing the more accurate acronym of RST as “wrist” or even as R-S-T.
