Mysteries of Vernacular is an interesting site that is developing a series of videos about the history and nuances of the English language. The concept is similar to that of Words of the World. Mysteries of Vernacular will eventually have one video for every letter of the alphabet. For now there is just a few videos available.
Applications for Education
Much like the idea I shared in my review of Words of the World, Mysteries of Vernacular could be an instructive model for your own lesson combining history and language
arts. Have your students pick a word or two that they think is common
and research it. Then have them create their own short videos in which
they explain the history of those words. You might even have them
research the dialect of the areas in which they live.
