By the early 16th century what was then called "Inglis" had become the language of government, and its speakers started to refer to it as "Scottis" and to Scottish Gaelic, which had previously been titled "Scottis", as "Erse" (Irish). The first known instance of this was by Adam Loutfut c. 1494. In 1559 William Nudrye was granted a monopoly by the court to produce school textbooks, two of which were "Ane Schort Introduction: Elementary Digestit into Sevin Breve Tables for the Commodius Expeditioun of Thame That are Desirous to Read and Write the Scottis Toung" and "Ane Intructioun for Bairnis to be Learnit in Scottis and Latin". In 1560 an English herald spoke to Mary of Guise and her councillors, at first they talked in the "Scottish tongue" but because he could not understand they continued in French.
