Celtic and the History of the English Language | Arrant Pedantry - http://www.arrantpedantry.com/2014...
"A little while ago a link to this list of 23 maps and charts on language went around on Twitter. It’s full of interesting stuff on linguistic diversity and the genetic relationships among languages, but there was one chart that bothered me: this one on the history of the English language by Sabio Lantz." - Maitani
"The first and largest problem is that the timeline makes it look as though English began with the Celts and then received later contributions from the Romans, Anglo-Saxons, Vikings, and so on. While this is a decent account of the migrations and conquests that have occurred in the last two thousand years, it’s not an accurate account of the history of the English language. (To be fair, the bar on the bottom gets it right, but it leaves out all the contributions from other languages.)" - Maitani
