YouTube channel featuring brief but informative animated videos on the history of written and spoken languages, linguistics, grammar and writing systems. The style is somewhat breathless but the content is academically sound and the enthusiasm of the presenter - whose interest in language ranges from Latin and Old Norse to Japanese and Tibetan - is infectious. Some of the content is strikingly original, such as an analysis of the grammar of an Islamic State communique in French about the attack on the Bataclan in Paris in November 2015 .
