Coronal “EIT wave” is a large-scale wavelike phenomenon propagating across the major part of the Sun. Debates are being continued regarding a more suitable name for it, its source driver, and its nature. “EIT waves” have been widely explained in terms of fast-mode waves, despite that the model contradicts with many observational features. Two-types of EUV waves were predicted 10 years ago. With the recent high-cadence observations, mainly from SDO/AIA telescope, more and more evidence has been revealed in favor of the two-wave model. In this paper, after summarizing different names used for EIT waves in the literature, we show how the community are getting close to reaching a consensus on the nature of EIT waves.
