In 15th and 16th century Scotland, in the highest courts of the land, you'd find esteemed poets hurling insults at each other. This was flyting, a sort of medieval equivalent of battle rap, and it was so popular at the time that the King himself wrote instructions for how to do it well. Writer and Scots language campaigner Ishbel McFarlane and historical linguist Joanna Kopaczyk explain the art of flyting, where an insult becomes slander, what's going on within the speech act of performative diss-trading, and what the legal consequences could be of being accused of witchcraft.
