Etymology
Scots is a contraction of Scottis, the Older Scots and northern version of late Old English: Scottisc (modern English "Scottish"), which replaced the earlier i-mutated version Scyttisc. Before the end of the fifteenth century, English speech in Scotland was known as "English" (written Ynglis or Inglis at the time), whereas "Scottish" (Scottis) referred to Gaelic. By the beginning of the fifteenth century, the English language used in Scotland had arguably become a distinct language, albeit one lacking a name which clearly distinguished it from all the other English variants and dialects spoken in Britain. From 1495, the term Scottis was increasingly used to refer to the Lowland vernacular: 894  and Erse, meaning "Irish", was used as a name for Gaelic. For example, towards the end of the fifteenth century, William Dunbar was using Erse to refer to Gaelic and, in the early sixteenth century, Gavin Douglas was using Scottis as a name for the Lowland vernacular. The Gaelic of Scotland is now usually called Scottish Gaelic.
